Artificial intelligence (AI) has potential to revolutionize radiology, yet current solutions and guidelines are predominantly focused on adult populations, often overlooking the specific requirements of children. This is important because children differ significantly from adults in terms of physiology, developmental stages, and clinical needs, necessitating tailored approaches for the safe and effective integration of AI tools. This multi-society position statement systematically addresses four critical pillars of AI adoption: (1) regulation and purchasing, (2) implementation and integration, (3) interpretation and post-market surveillance, and (4) education. We propose pediatric-specific safety ratings, inclusion of datasets from diverse pediatric populations, quantifiable transparency metrics, and explainability of models to mitigate biases and ensure AI systems are appropriate for use in children. Risk assessment, dataset diversity, transparency, and cybersecurity are important steps in regulation and purchasing. For successful implementation, a phased strategy is recommended, involving early pilot testing, stakeholder engagement, and comprehensive post-market surveillance with continuous monitoring of defined performance benchmarks. Clear protocols for managing discrepancies and adverse incident reporting are essential to maintain trust and safety. Moreover, we emphasize the need for foundational AI literacy courses for all healthcare professionals which include pediatric safety considerations, alongside specialized training for those directly involved in pediatric imaging. Public and patient engagement is crucial to foster understanding and acceptance of AI in pediatric radiology. Ultimately, we advocate for a child-centered framework for AI integration, ensuring that the distinct needs of children are prioritized and that their safety, accuracy, and overall well-being are safeguarded.
Background Uterine rudiments are present in up to 50% of Mayer-Rokitansky-Küster-Hauser syndrome casesObjective: To describe the clinical course of cases of uterovaginal agenesis with symptomatic and asymptomatic Mullerian remnants This series highlights the importance of early diagnosis and individualized surgical management. Case or Series Two of the four cases presented with cyclic pelvic pain associated with functional rudimentary uterine horns and secondary endometriosis. Imaging (ultrasound, MRI, and CT) confirmed uterine abnormalities, with findings of uterine agenesis, rudimentary uterine horns, and associated renal malformations in one case. All patients underwent diagnostic laparoscopy, and three underwent excision of rudimentary uterine horns. Histological findings included adenomyosis and endometriosis in symptomatic patients. Comments Functioning uterine rudiments can cause cyclical pain and promote endometriosis. Early diagnosis and comprehensive follow-up are key to long-term prognosis.
OBJECTIVES:To characterize the magnetic resonance imaging (MRI) lesion dynamics, comorbidities, predictors of relapse, and outcomes in anti-γ-aminobutyric acid type A receptor (GABAAR) encephalitis, and assess the utility of LIM-domain-only-protein 5 (LMO5) antibodies as tumor markers. METHODS:GABAAR antibodies were confirmed by 2 techniques in serum or cerebrospinal fluid. Long-term outcomes were defined as good (modified Rankin scale, mRS = 0-1) or poor (mRS 2-5) at ≥12 months. LMO5 antibodies were assessed by cell-based assays and Western blot. RESULTS:Thirty-three patients were identified (4 children, 29 adults; median age, 5.5 and 60 years; 61% male). Ten patients (10/32, 31%) had concurrent systemic autoimmunity. Adults presented with seizures and cognitive/behavioral symptoms, often with thymoma, gastrointestinal, or other tumors (18/33, 55%), whereas children frequently had seizures and ataxia with cerebellar MRI lesions. Multifocal T2/fluid-attenuated inversion recovery hyperintensities were present at onset in 23 of 31 (74%) or developed later in those with absent or single lesions. Lesions showed dynamic changes, suggesting ongoing inflammation even without clinical correlate. Relapses occurred in 17 of 31 (55%, all adults) and were associated with older age (p = 0.02) and lack of second-line immunotherapy (p = 0.02). Four patients (4/33, 12%) died. After a 32.5-month median follow-up, 9 of 20 (45%) had persistent cognitive deficits, and 6 of 20 (30%) had a poor outcome, which was associated with relapses (p = 0.04). LMO5 antibodies were absent in patients and controls. INTERPRETATION:Anti-GABAAR encephalitis shows age-dependent presentations, most commonly seizures. MRI reveals dynamic changes consistent with an ongoing "clinically silent" inflammation. Relapses and cognitive sequelae are common and associate with not receiving second-line immunotherapy. LMO5 antibodies lack tumor-predictive value. ANN NEUROL 2026;100:139-150.
Background and Clinical Significance: IgG4-related disease (IgG4-RD) is a chronic fibroinflammatory, immune-mediated multisystem disorder that can mimic neoplastic, infectious, or autoimmune conditions. Among its head-and-neck manifestations, IgG4-related dacryoadenitis and sialadenitis, historically referred to as Mikulicz disease, should be distinguished from the classical Mikulicz syndrome, which describes secondary lacrimal and salivary gland enlargement due to other systemic disorders. Renal involvement, most commonly in the form of IgG4-related tubulointerstitial nephritis (IgG4-TIN), is less frequent but carries major prognostic implications because delayed diagnosis may lead to irreversible kidney damage. Case Presentation: A 49-year-old man with no relevant past medical history presented with a 2-year history of intermittent polyuria and foamy urine. Laboratory testing revealed advanced kidney dysfunction, with serum creatinine of 4.2 mg/dL, estimated glomerular filtration rate of 16 mL/min/1.73 m2, and proteinuria of 2874 mg/day. Physical examination showed bilateral parotid enlargement, upper eyelid edema, lacrimal gland enlargement, and sicca symptoms, raising suspicion for IgG4-related dacryoadenitis and sialadenitis (Mikulicz disease). Further work-up demonstrated marked eosinophilia, polyclonal hypergammaglobulinemia, and significantly elevated serum IgG4 levels (3180 mg/dL), while infectious serologies and autoimmune studies were negative. Kidney biopsy revealed plasma cell-rich tubulointerstitial nephritis with lymphoplasmacytic and eosinophilic infiltrates, interstitial fibrosis, tubular atrophy, and more than 40 IgG4-positive plasma cells per high-power field, supporting the diagnosis of IgG4-related tubulointerstitial nephritis in the setting of systemic IgG4-RD. Treatment with prednisone followed by mycophenolate mofetil led to improvement in glandular manifestations and a partial reduction in proteinuria, but renal recovery remained incomplete. The patient subsequently developed a severe pulmonary infection complicated by sepsis and oligoanuric acute kidney injury superimposed on chronic kidney disease, and ultimately progressed to end-stage kidney disease requiring chronic maintenance hemodialysis. Conclusions: This case highlights that a Mikulicz disease phenotype may represent the initial manifestation of systemic IgG4-RD and should prompt evaluation for extraglandular involvement, particularly renal disease. In patients with glandular enlargement, eosinophilia, hypergammaglobulinemia, and unexplained renal dysfunction, IgG4-RD should be actively considered. Kidney biopsy remains essential for diagnostic confirmation and prognostic assessment, as delayed recognition may result in irreversible renal damage and progression to end-stage kidney disease.
