Background Lung cancer (LC) is linked to an increased risk of cancer-associated thrombosis (L-CAT), requiring anticoagulant therapy (AT). Patients treated with AT have an increased risk of bleeding. Hemoptysis is common and potentially severe in LC patients. The risk of hemoptysis in L-CAT patients who initiated AT remains unknown. Method A retrospective observational study was conducted in patients with L-CAT who initiated AT, from January 1, 2010, to December 31, 2022. The primary aim was to determine the incidence of hemoptysis within 6 months of follow-up. Secondary aims were to assess risk factors for hemoptysis, its clinical impact, and its association with 6-month mortality. Result Among 108 L-CAT patients, 9 developed a hemoptysis at 6 months (8.33%, 95% CI [3.12-13.54]). Main risk factors identified were history of bleeding (OR 16.88, 95% CI [3.68-77.30]), tumor size >7cm (OR 5.29, 95% CI [1.34-20.85]), squamous cell carcinoma (OR 4.48 [1.15-17.42), endobronchial bud at endoscopy (OR 10.81 [2.05-74.18]). The median time to hemoptysis onset was 9 days. Events were of low abundance, recurrent and non-fatal. Two patients required hospital admission, one of whom needed aerosol vasopressin therapy. Relative risk of death at 6 months was 1.29, (CI 95% [0.80-2.07]) in patients with hemoptysis, compared to those without. Conclusion Nearly one in ten patients with L-CAT experienced hemoptysis, typically within the first days of treatment. Though generally non-severe and not directly fatal, these events highlight the need for close monitoring. Further research is needed to clarify the impact on prognosis.

Introduction: The estimation of the patient's peak skin dose (PSD) in interventional radiology is essential for assessing deterministic risks. In this context, more and more software solutions offer a calculation of the patient's PSD. The aim of this study is to compare the PSD calculated by the Skin Dose Map (SDM) module of DoseWatch (R) in interventional radiology with that evaluated using radiochromic films during clinical acts. Methods: The PSDs calculated by the SDM were compared with those estimated with Gafchromic (R) films XR-RV3 (previously calibrated using an EPSON (R) Expression 10,000XL scanner) during clinical acts, employing a rigorous methodology to minimize uncertainties. Results: In total, 66 Gafchromic (R) films were used to determine the PSD. For the whole of the procedures studied, the average deviation of the PSD was equal to -27%. However, the results were noticeably different between the interventional neuroradiology procedures of the head and the interventional imaging of the trunk. Indeed, the average deviations were equal to -18% and -32%, respectively. Conclusion: Although the average deviation observed in our sample is quite large, the SDM module from DoseWatch (R) remains an important tool in preventing risks of determining effects. Implications for practice: These results encourage the implementation of verification tests for these PSD calculation software and, in some cases, to define lower alert thresholds.

IntroductionLateral ankle sprain (LAS) is the most common orthopaedic injury, yet initial diagnosis often lacks precision, leading to suboptimal management and persistent symptoms. This study aimed to compare findings from routine clinical tests with magnetic resonance imaging (MRI) results following LAS.MethodsPatients presenting with LAS were re-evaluated 7 to 10 days post-injury using standardized clinical tests. Ligaments assessed included the anterior talo-fibular (ATFL), calcaneo-fibular (CFL), antero-inferior tibiofibular (AITFL), interosseous talo-calcaneal (ITCL), and superficial and deep deltoid ligaments (sDL, dDL). Specific tests included Anterior Drawer Test (ADT) for ATFL; Varus Talar Tilt Test (VTTT) for CFL; palpation pain for ATFL, CFL, ITCL, and DL; VTTT in dorsiflexion and sinus tarsi pain for ITCL; medial malleolus and deltoid pain for DL; Squeeze Test, External Rotation Test, and syndesmosis pain for AITFL. The MRI performed within 3 weeks served as the reference standard. Sensitivity (Se) and specificity (Sp) were calculated for each individual and combined test per ligament. Results. Isolated ATFL ± CFL injuries were found in 50% of cases. Combined tests showed the highest sensitivity. "Pain on palpation" was the most reliable test for ATFL, CFL, and ITCL (Se/Sp: 100%/33.3%, 70.8%/56.2%, 70.8%/56.2%). Dynamic tests like ADT, VTTT, and VTTT in dorsiflexion showed limited diagnostic value (Se/Sp: 58.8%/66.7%, 29.2%/68.8%, 29.2%/68.8%). For sDL and dDL, "pain on deltoid" had low sensitivity but high specificity (0%/84.2 and 44.4%/93.5%). Squeeze and External Rotation Tests were poor for general AITFL injuries (0%/84.2%) but highly accurate for unstable syndesmosis (100%/91.9%).ConclusionLateral ankle sprains often involve more than just the lateral ligament complex. Clinical tests alone lack accuracy, particularly for deltoid and AITFL injuries. Combining tests improves sensitivity. Suspicion of syndesmosis, subtalar, or medial injury should prompt further imaging due to the low sensitivity of clinical evaluation.

Colorectal cancer (CRC) is the third most common malignancy worldwide, and early detection is vital to prevent metastasis and postoperative recurrence. This review summarizes current applications of spectral computed tomography (CT) in CRC, including its principles, spectral parameters used for evaluating primary and metastatic lesions, and key findings from recent literature. A systematic search of PubMed, Web of Science, and Google Scholar identified English-language studies published between April 2018 and April 2025 using the keywords: “spectral CT,” “spectral imaging,” “dual-layer spectral CT,” “dual-energy spectral CT,” “colorectal cancer,” and “colon cancer.” Spectral CT has shown promise in improving CRC detection and T staging accuracy, increasing sensitivity for lesion characterization, and aiding prognostic assessment after chemotherapy using baseline spectral parameters. Early evidence suggests it may also help predict lymph node metastasis and identify patients at risk of early postoperative metastases or surgical complications. Spectral parameters have been correlated with KRAS mutation, Ki-67 index, microsatellite instability, lymphovascular, perineural, and extramural vascular invasion, as well as microvessel density. However, most studies remain small and observational, highlighting the need for validation in larger, multicenter cohorts. Standardization and the time-intensive nature of image segmentation currently limit widespread adoption. Nevertheless, spectral CT is expected to play an increasing role in CRC evaluation by providing quantitative, predictive imaging biomarkers. Integration with artificial intelligence, particularly deep learning and automated segmentation, will likely expand both research and clinical applications. This article explores the current applications of spectral CT in colorectal cancer by outlining the fundamentals of spectral CT, the spectral parameters used to assess, stage, and predict the prognosis of primary and metastatic disease, as well as the main findings from the current literature.

Achieving secondary resectability remains a major challenge in patients with initially unresectable colorectal liver metastases (CRLM). We report a 46-year-old patient with rectal adenocarcinoma and three large synchronous unresectable liver metastases who achieved a durable response following an intensive multimodal strategy. FOLFOX plus panitumumab induced partial regression, while selective internal radiation therapy (SIRT) led to extensive tumor necrosis, enabling curative-intent extended left hepatectomy combined with microwave ablation. The patient remains in remission without systemic therapy more than six months after treatment completion. This case highlights the role of SIRT in conversion strategies for large oligometastatic CRLM.

PURPOSE:To evaluate the feasibility, safety, and early outcomes of percutaneous image-guided screw fixation (PIGSF) for radiation-induced pelvic insufficiency fractures (R-PIFs). MATERIALS AND METHODS:This study retrospectively analyzed consecutive patients with symptomatic R-PIFs treated by PIGSF under computed tomography (CT) or cone-beam CT guidance between January 2021 and January 2024 in 3 tertiary centers. Screws were positioned via transsacroiliac approaches, with cement injected into the fracture site and screw trajectory. Clinical evaluation included pain, analgesic use, mobility, and patient-reported quality of life (QoL). Follow-up included standardized consultation and CT at 1 month. RESULTS:Eighteen patients (mean age, 71.0 years [SD ± 6.5]; women, 61%) were included. Technical success was achieved in all interventions, with a median procedure duration of 63 minutes (range, 45-90 minutes). A total of 32 screws were implanted (mean, 1.8 per procedure). No intraoperative or early adverse events occurred. All patients were able to stand up and walk within 24 hours, and 17 of 18 were discharged on Day 1. At 1 month, maximal pain intensity decreased from 8.6 (SD ± 1.8) to 3.3 (SD ± 2.8) (P < .0001), and mean pain intensity decreased from 7.2 (SD ± 2.0) to 2.0 (SD ± 1.8) (P < .0001). QoL improved from 40.0 (SD ± 22.4) to 72.3 (SD ± 22.4) (P = .0036). CONCLUSIONS:PIGSF for R-PIFs is technically feasible, safe, and associated with rapid pain relief, early mobilization, and improved QoL.

PURPOSE:To evaluate the safety, feasibility, and early clinical outcomes of combined percutaneous cryoablation, screw fixation, and cementoplasty for painful pelvic bone metastases. MATERIALS AND METHODS:In this monocentric retrospective study, patients with painful pelvic bone metastases underwent percutaneous image-guided cryoablation followed by screw fixation and cementoplasty under computed tomography (CT) guidance. Technical success was defined as completion of all planned procedural steps without deviation. Clinical endpoints included adverse events, mobilization, discharge timing, pain, analgesic use, and quality of life. Imaging follow-up assessed screw stability, infection, local tumor behavior, and progression to joint replacement when applicable. RESULTS:Seventeen patients were included. Technical success was achieved in all procedures. Cryoablation required a mean of 2.7 probes (SD ± 1.3), and 1.2 screws (SD ± 0.4) were implanted per procedure. Complete planned soft tissue ablation was achieved in 11 patients (64.7%), including complete combined bone and soft tissue ablation in 5 (29.4%); partial ablation/debulking was intentionally planned in the remaining 6 (35.3%). No periprocedural or early adverse events occurred. Thirteen patients (76.5%) were able to stand within 24 hours, and all within 4 days. Eight patients (47.1%) were discharged on postoperative Day 1, and 13 (76.5%) within 2 days. No patient required joint replacement during available follow-up. Median overall survival was approximately 150 days. CONCLUSIONS:A combination of percutaneous cryoablation, screw fixation, and cementoplasty is feasible and safe and provides rapid early clinical benefit in selected patients with pelvic metastases. Larger comparative studies are required to confirm effectiveness and long-term joint-related outcomes.

To systematically review the available evidence on the feasibility, safety, and clinical effectiveness of percutaneous sclerotherapy using radiopaque gelified ethanol (RGE, Discogel®) for bone lesions. A systematic search of MEDLINE, Embase, Web of Science, and Cochrane CENTRAL was performed. Primary studies reporting clinical, technical, and safety outcomes following RGE sclerotherapy for bone lesions were included. Data on patient characteristics, lesion type, procedural details, and outcomes were extracted and synthesized descriptively. Six retrospective studies involving 55 patients (mean age 22.2 ± 20.4 years; range 3–65; 26 females) with 56 lesions and 119 procedures were included (mean 2.16 procedures per patient). Aneurysmal bone cysts (80

INTRODUCTION:Esophagectomy and pancreatectomy are invasive oncological surgeries with elevated mortality rates. Preoperative muscle mass deficit and myosteatosis, identifiable on L3 CT-scan, could be associated with poor postoperative outcomes in cancer patients. We aimed to determine their impact on short-term complications following esophageal or pancreatic cancer resection. METHODS:We conducted a retrospective cohort study in two hospital centers from January 2018 to February 2023. Adult patients undergoing esophagectomy or pancreatectomy for cancer with a preoperative CT scan at L3 level were included. Muscle skeletal mass and quality were assessed using previously published thresholds. Poor postoperative short-term outcomes were defined as the occurrence of sepsis, septic shock, or death within 90 days postoperatively. RESULTS:Of 216 patients, 165 patients were eligible for muscle mass analysis and 143 for muscle quality assessment. Poor short outcome occurred in 55 patients (33.3%). Surprisingly, skeletal muscle depletion was inversely associated with poor outcomes in the multivariate logistic regression model (OR 0.38, 95% CI [0.15-0.97], p = 0.04). Myosteatosis was associated with a significantly 6-fold increased risk of poor short-term outcomes in univariate analysis (OR 6.04, 95% CI [2.35-15.55], p < 0.001), with a persistent trend in the multivariate logistic regression model (OR 3.51, 95% CI [0.99-12.39], p = 0.05). In the ICU subgroup, patients with preoperative skeletal muscle depletion and myosteatosis had higher 28-day mortality than those with preserved muscle mass and quality. CONCLUSION:Myosteatosis, rather than muscle mass deficit, showed a strong trend toward association with adverse postoperative short-term outcomes following esophagectomy and pancreatectomy. Defining population-specific thresholds for CT scan muscle assessment are necessary to improve the use of L3 scans for short-term outcome risk evaluation in oncologic surgery.

BACKGROUND:Subtalar ligament injuries occur in 10-25% of lateral ankle sprains (LAS) but remain underdiagnosed, partly because their radiological anatomy is insufficiently defined. PURPOSE:This anatomo-radiological study aimed to systematically characterize the MRI appearance and anatomical morphology of the principal subtalar ligaments. STUDY DESIGN:Descriptive, single-center anatomo-radiological reference study (Level IV). METHODS:Seventeen patients underwent 3-Tesla 3D-MRI of the contralateral asymptomatic ankle after lateral ankle ligament repair. The inferior extensor retinaculum (IER), cervical ligament (CL), interosseous talocalcaneal ligament (ITCL), and calcaneofibular ligament (CFL) were evaluated on multiplanar reconstructions aligned with each ligament's axis. Length, width, and thickness were measured in all cases. RESULTS:The mean age of the cohort was 35 ± 12.5 years; 7 women and 10 men were included, with a mean BMI of 28 ± 6.3 kg/m². All four ligaments were consistently visualized on 3D-MRI. Length, width, and thickness measured 34.6 ± 6.8, 5.6 ± 1.2, and 1.7 ± 0.2 mm for the IER; 19.0 ± 1.6, 5.3 ± 1.3, and 1.8 ± 0.5 mm for the CL; 16.9 ± 2.4, 10.0 ± 1.4, and 2.4 ± 0.9 mm for the ITCL; and 25.2 ± 4.8, 5.8 ± 2.0, and 2.8 ± 0.6 mm for the CFL. CONCLUSIONS:This study provides reference identification methods and normative measurement values for 3D-MRI assessment of the IER, CL, ITCL, and CFL. These data improve the understanding of subtalar ligament morphology and may aid in the diagnosis and treatment of subtalar ligament injuries.

Minimal ablative margins (MAM) are critical for local tumour control after microwave ablation, yet their assessment remains subjective. We evaluated whether software improves the precision of ablation margin assessment after liver MWA. In this retrospective study, patients undergoing CT-guided liver MWA between January 2019 and January 2025 were included. Two radiologists (with 4 and 5 years of experience in abdominal imaging) assessed MAM in two steps: first by side-by-side visual comparison of pre- and post-ablation CT using anatomical landmarks, then with dedicated software providing semi-automatic 3D co-registration and margin quantification. Each method included two reading sessions per reader, six weeks apart. Precision was assessed using intraclass correlation coefficients (ICC), Cohen’s kappa (κ) for categorical classification (< 5, 5–10, > 10 mm), and Bland–Altman analysis. Sixty-seven patients with 87 liver tumours were included. Visual assessment showed poor reliability, with low intrareader agreement (ICC 0.10 and 0.33) and near-random interreader agreement (κ = − 0.10; ICC − 0.05), with limits of agreement approaching 17 mm. Software-assisted assessment improved reliability, with higher intrareader ICCs (0.54 and 0.83) and improved interreader agreement (κ = 0.38; ICC = 0.54). Interreader bias decreased from − 2.84 to + 0.91 mm, and limits of agreement narrowed to − 4.10 to + 5.92 mm (p < 0.001). The median absolute interreader difference decreased from 3.0 to 1.0 mm (p < 0.001). Software-assisted assessment improves reliability of MAM evaluation compared with visual methods, but interreader agreement remains only fair-to-moderate; further validation is required before routine clinical adoption.

To identify predictors of 30-day mortality and derive a bedside risk score in patients with computed tomography (CT)-proven active bleeding and negative emergency angiography. We retrospectively included consecutive adults with CT-detected active bleeding and negative emergency angiography in a single-center cohort (2012–2026). Univariate analyses (Fisher exact, Mann–Whitney U) were followed by multivariable logistic regression, with a LASSO-penalized model (fivefold cross-validation) performed as sensitivity analysis. A simplified score, Negative Angiography Bleeding–Lethality (NAB-L), was derived from regression coefficients. Discrimination was assessed by area under the receiver operating characteristic curve (AUC) with bootstrap internal validation, calibration by the Hosmer–Lemeshow test, and survival by Kaplan–Meier methods with log-rank comparison. A total of 118 patients were included (median age 67.5 years [IQR 51–78]; 55

INTRODUCTION:We evaluated whether computed tomography (CT)-based body composition parameters predict outcomes after hyperthermic intraperitoneal chemotherapy (CRS ± HIPEC) for gastric peritoneal metastases (GPM). METHODS:A retrospective analysis of a prospectively maintained single-centre database included consecutive patients undergoing CRS ± HIPEC for GPM between January 2014 and December 2024. Skeletal muscle index (SMI), muscle radiodensity, and adipose tissue parameters were quantified on preoperative CT at the third lumbar vertebra. Sarcopenia was defined using validated sex-specific cut-offs. Postoperative complications, progression-free survival (PFS), and overall survival (OS) were analysed using multivariable regression and sensitivity analyses based on alternative sarcopenia definitions. RESULTS:Among 108 procedures performed in 106 included patients, 36 (33%) were sarcopenic. Major complications did not differ significantly (44% vs 39%; OR 1.26, 95% CI 0.56-2.83; p = 0.679), although moderate differences could not be excluded. In the overall cohort, neither PFS nor OS differed significantly according to sarcopenia status. However, among patients with synchronous GPM, sarcopenia was associated with shorter OS (median 10.2 vs 16.3 months; HR 1.85, 95% CI 1.05-3.25; p = 0.033), with a consistent but non-significant multivariable trend (p = 0.061). An adjusted interaction analysis supported effect modification according to disease timing (p for interaction = 0.043). Sensitivity analyses using four alternative sarcopenia definitions yielded consistent findings. CONCLUSION:Preoperative CT-defined sarcopenia identifies patients with synchronous GPM at higher risk of poor overall survival after CRS ± HIPEC without a detectable increase in postoperative morbidity. CT-based body composition may improve preoperative prognostic stratification and help identify candidates for future studies of nutritional optimisation or multimodal prehabilitation.

The purpose of the present study is to determine whether or not lesion characteristics on PET/CT could reduce the number of samples required to achieve a diagnosis in image-guided bone biopsies (IGBB). A retrospective review of 38 percutaneous IGBB performed at a single center. Biopsies have been performed from January 1st, 2020, to October 23rd, 2024. Inclusion criteria were patients with a PET/CT and a histopathologic report available. Specimens were collected, numbered, and independently analyzed in separate containers. PET/CT data, including SUVmax, SUVmean, MTV, TLG, and morphological lesion characteristics, were correlated with biopsy outcomes and subjected to statistical analysis. Patients were classified by the number of samples needed for diagnosis: first (Group 1), second (Group 2), or third/subsequent (Group 3). Thirty-four/38 (89

PURPOSE:To evaluate the safety and effectiveness of image-guided cementoplasty, with or without screw fixation, for treating pelvic bony lesions in patients aged 70 years and older. MATERIALS AND METHODS:This single-center retrospective study included all image-guided cementoplasties, with or without screw fixation, performed between June 2018 and November 2022 for the management of pelvic osteoporotic fractures or neoplastic lesions in patients aged 70 years and older. RESULTS:A total of 46 interventions were successfully performed, including 8 for osteoporotic fractures and 38 for neoplastic lesions. No major procedure-related adverse events were observed. Among the 36 cases assessed, 25 (69.4%) patients either switched to a lower analgesic level or reduced their analgesic consumption within 1 month postprocedurally. Specifically, 14 of 25 (56.0%) patients required less potent analgesic drugs, while 11 of 25 (44.0%) reduced their daily dose of the same analgesic drug. The proportion of patients able to stand increased from 21 of 44 (47.7%) to 41 of 44 (93.2%), while the proportion able to walk rose from 21 of 44 (47.7%) to 40 of 44 (90.9%). CONCLUSIONS:Percutaneous cementoplasty, with or without screw fixation, is a safe and effective technique for managing pelvic lesions in patients aged 70 years and older. It results in significant pain reduction and facilitates early mobilization, with most patients able to stand the day after the procedure.

To objectively evaluate quantitative image parameters—signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR)—of peritoneal metastases (PMs) from colorectal cancer (CRC) on virtual monoenergetic images (VMIs) reconstructed from dual-layer spectral CT (DLCT) technology. This prospective single-center study included consecutive patients scheduled for cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) between September 1, 2023, and May 1, 2025. All patients underwent contrast-enhanced DLCT < 7 days before surgery. SNR, CNR between PMs and mesenteric fat (CNR MF), CNR between PMs and adjacent organ (CNR AO) were calculated on VMIs ranging from 40 to 200 keV. PMs were classified as mucinous (mPMs) or non-mucinous (nmPMs) based on histopathology. PM conspicuity and sharpness were also evaluated between 40 and 120 keV. A total of 92 PMs (24 mPMs, 68 nmPMs) in 55 patients were analyzed. For both mPMs and nmPMs, attenuation, SNR, CNR MF, CNR AO, were highest at 40 keV (42.47 ± 23.81, 3.00 ± 2.01, 12.36 ± 3.78, 7.30 ± 3.71, and 131.16 ± 50.17, 9.88 ± 5.38, 21.89 ± 10.57, 5.62 ± 3.07, respectively) and decreased with increasing energy levels. In nmPMs, CNRAO and SNR declined significantly from at 50 keV onward (p < 0.05). Image noise remained stable across the 40–200 keV range. PM conspicuity and sharpness were significantly higher at 40 keV (p < 0.05). Low-energy VMIs obtained from spectral CT significantly improve SNR and CNR of PMs, particularly for nmPMs, supporting their integration into preoperative reading protocols.

PURPOSE:The purpose of this prospective study was to evaluate the diagnostic performance of dual-energy computed tomography (DECT) using a dual-layer detector scanner in assessing the pathological response of peritoneal metastases (PMs) from non-mucinous colorectal cancer to neoadjuvant chemotherapy (NAC). MATERIALS AND METHODS:Consecutive patients with PMs from non-mucinous colorectal cancer who underwent preoperative DECT using a dual-layer detector scanner before cytoreductive surgery were prospectively included. Virtual monoenergetic images at 40 keV (VMI40kev), VMIs at 100 keV (VMI100kev), VMI slope (VMIslope), iodine concentration (IC), normalized iodine concentration with aorta (nICaorta) and liver (nICliver), effective Z atomic number (Zeff), and extracellular volume fraction (ECVf) were evaluated on PMs by two radiologists. Pathological response of PM was classified using the peritoneal regression grading score (PRGS), and classified as either good (complete response or major histological regression - PRGS ½) or poor (minor or no histological response - PRGS ¾) responses. DECT variables of PMs with good responses were compared to those of PMs with poor responses using independent-sample t-tests. Receiver operating characteristic curves were built to estimate the capabilities of the different DECT variables in differentiating between PMs with good responses (PRGS ½) and those with poor responses (PRGS ¾). Intra-class correlation coefficients analyses were performed to estimate interobserver variability in DECT variable measurements. RESULTS:Forty-four patients (22 men median age, 62 years; age range: 35-78 years) with 77 PM were included from September 1st 2023 to July 1st 2025. Thirty-nine out of 77 PMs (51 %) exhibited good response (PRGS ½) and 38 PMs (49 %) exhibited poor response (PRGS ¾). VMI40kev, VMIslope, IC, nICaorta, nICliver, ECVf were significantly greater in PRGS ¾ PMs by comparison with PRGS ½ (P < 0.05). The best AUC values to distinguish between good and poor pathological response of PMs were obtained with nICaorta (AUC, 0.74: 95 % confidence interval [CI]: 0.63-0.85) and ECVf (AUC, 0.74; 95 % CI: 0.63-0.84). ICC was > 0.8 for most DECT variables. CONCLUSION:DECT using a dual-layer detector scanner provides promising biomarkers for predicting pathological response in non-mucinous PM after chemotherapy.

Introduction Chaque structure ligamentaire joue un rôle spécifique dans la coordination du genou lors des mouvements dans l’espace. Le ligament antérolatéral (LAL), récemment identifié, est crucial dans le contrôle rotatoire conjointement au ligament croisé antérieur (LCA). Données récentes La découverte de ce ligament a amélioré les techniques de reconstruction du LCA. La reconstruction du LAL est désormais une intervention chirurgicale orthopédique essentielle pour optimiser le traitement des lésions du LCA et semble devenir une alternative à la ténodèse latérale extra-articulaire qui, selon certaines biomécaniques, induit une surcontrainte de la rotation interne. L’imagerie médicale joue un rôle clé dans le diagnostic préopératoire, la planification chirurgicale et le suivi postopératoire de cette procédure. En effet, l’IRM offre une évaluation postopératoire précise de la ligamentoplastie, notamment de sa position, du diamètre et de l’angle des tunnels osseux tibiaux et fémoraux. Conclusion Il est primordial de comprendre en détail les caractéristiques anatomiques et radiologiques pré- et postopératoires du LAL, ainsi que son rôle dans la prise en charge chirurgicale des ruptures du LCA.

A 57-year-old woman had an incidental finding of a hypervascular small bowel lesion on a contrast-enhanced CT scan performed for a suspected renal graft infection. The morphologic features of the lesion were suggestive of a neuroendocrine tumor (NET), but serum chromogranin A and urinary 5-HIAA were negative. 68 Ga-DOTATOC PET/CT showed high SSTR-2 expression in the lesion, suggesting a NET. However, pathologic examination revealed diffuse alpha-smooth muscle actin positivity, consistent with a glomus tumor. This case highlights the utility of PET/CT for in vivo molecular tumor characterization and the challenge of distinguishing between different tumor types with overlapping molecular targets.

Aneurysmal bone cysts are locally aggressive bone lesions. The aim of this study was to evaluate safety and effectiveness of radio-opaque gelified ethanol sclerotherapy in treating primary aneurysmal bone cyst. In this single-center, retrospective study (January 1st, 2012, to June 30th, 2024), 32 patients with primary aneurysmal bone cysts were treated with percutaneous sclerotherapy using radio-opaque gelified ethanol at various skeletal sites. Of these, 27 patients were included in the analysis, 5 patients were excluded due to follow-up of less than 12 months. The primary outcome measure was the safety of the procedures. Secondary outcomes measures included clinical success, defined as the absence of post-sclerotherapy fractures or the need for surgical revision, and radiological success, determined by the conversion of an active or aggressive aneurysmal bone cyst to inactive, according to Campanacci's classification. No major complications related to the procedure were observed. One minor complication (3.7
