OBJECTIVE:To investigate ultrasound and MRI features of malignant fibrous histiocytoma (MFH) of soft tissue.METHODS:Ultrasound, MRI images and pathological data of 12 patients with malignant fibrous histiocytoma in soft tissue confirmed by operation and pathology were analyzed from January 2012 to August 2018, inlcuding 7 males and 5 females, aged from 36 to 69 years old with an average age of 53 years old; the courses of disease ranged from 4 to 49 months with an average of 28 months. Clinical manifestations were soft tissue masses and pain in the affected limbs. Ultrasound, MRI and contrast-enhanced examination were performed before operation. The lesions, morphology, echo/signal characteristics, color flow signals and enhancement features were observed and compared with pathology.RESULTS:In 12 patients with MFH, 9 patients were primary lesions and 3 patients were recurrent lesions after operation. There were 7 cases of bilateral thighs, 2 cases of calves, 1 case of upper arm, 1 case of buttocks and 1 case of posterior peritoneum. The size ranged from 5.1 to 17.1 cm with an average of 8.7 cm. Ultrasound feature showed lobulated or agglomerate, and focused on low echo; 5 cases had capsule and with clear border; 7 cases were unclear boundary with surrounding tissues; and 6 cases with irregular echo-free. The blood flow signals were around the CDFI, and the internal blood flow signals were different. MRI feature showed lobulated, agglomerate or irregular shape, T1WI showed slightly lower signal or equal signal, T2WI showed high signal and DWI signal increased. Six patients manifested mixed signal inside, 7 patients manifested low signal separation inside, 5 patients with false envelope, and 9 patients manifested infiltration and growth with peripheral edema. T1WI showed uneven strengthening after enhancement. Immunohistochemical expression of Vim, CD68 were positive.CONCLUSIONS:The age, location and imaging features of soft tissue MFH are characteristic. The diagnosis of MFH should be considered when irregular mass occurred in soft tissues of limbs at middle-aged and old people. Echo and signal are homogeneous or mixed. Separation, necrosis and cystic degeneration could be seen in the mass. When the blood flow signals are abundant and solid components are obviously enhanced, the diagnosis of MFH should be considered.

随着高频超声技术的发展及国民健康体检意识的增强,甲状腺结节的超声检出率逐年上升,其中约5%~15%的结节为恶性,因此准确评估甲状腺结节的良恶性非常重要[1-2].甲状腺细针穿刺(fine needle aspiration biopsy,FNAB)是一项安全、经济、可靠的检查方法,如何提高甲状腺结节细针穿刺取材成功率、减少并发症一直是临床工作的重点与难点.既往文献关于负压吸引甲状腺细针穿刺的运用报道较多,但是普遍存在红细胞污染率高、并发症多的问题,取材成功率不高[3-5].本文为避免红细胞污染细胞学涂片,减少穿刺出血,将Adler血流分级运用于甲状腺结节细针穿刺中,探讨其临床运用价值.

诊断乳腺疾病目前常用的是超声和X线钼靶摄影, X线钼靶发现乳腺肿块率较高,但鉴别其良恶性准确性不很高,且受辐射线照射对身体有损害。乳腺常规超声检查是目前诊断乳腺疾病最常用的方法,对良恶性作出初步诊断,但不能了解肿块的软硬度,而乳腺肿块的硬度与良恶性相关,学者普遍认为肿块质地较软的多为良性,较硬的多为恶性肿块。最新的超声弹性成像技术突破了这一观念,认为乳腺良、恶性肿块有弹性差异,利用肿块本身具有的弹性差异对鉴别良、恶性有重要临床意义,因此,超声弹性成像已成为乳腺肿块诊断的新方法。本文对此作一探讨。
Objective To compare the use of 16G and 18G biopsy needles in percutaneous ultrasound- guided renal biopsy. Methods Four hundred and eighty six patients undergoing percutaneous ultrasound- guided renal biopsy were as-signed to use 16G Cru- cut biopsy needle (n=216) or 18G needle (n=270). Two specimens of renal tissue were required to be taken for 16G group and 3 specimens were required for 18G group. Results The overal success rate of biopsy was 94.4%, that was 93.6%in 16G group and 95.2%in 18G group (P>0.05). The average biopsy times in 16G group was 2.57±0.34 and that in 18G group was 2.84±0.51(P<0.01). The complication rate in G16 group was 8.80%(gross hematuria 5.56%, subcapsular renal hematoma 3.24%) and that in G18 group was 5.56%(gross hematuria 4.07%, subcapsular renal hematoma 1.48%) (P>0.05). The average number of glomerulum under light microscope in 16G group was 19.33 ±4.91and that in 18G group was 25.27±6.23 (P<0.05). Conclusion Ultrasound- guided renal biopsies using 18G Cru- cut biopsy needle does not increase the incidence of complications, although one more specimen need to be taken compared to using 16G. The specimens of renal tis-sue taken using both needles meet standard of light, immunofluorescence and electron microscopic examinations.
乳腺癌是危害妇女健康和生命的最常见的恶性肿瘤.发病率有逐年增加的趋势[1],在各种检查手段中,超声是乳腺肿块良恶性检查中的首选影像学检查方法,但二维超声成像技术及彩色多普勒超声成像技术在对肿块做出良恶性鉴定时仍有局限性[2].超声弹性成像是近年发展起来的一种成像方法,其可通过提取病变的硬度信息对病灶进行良恶性鉴别诊断,这一技术目前在乳腺疾病诊断中的应用最广泛[3].作者回顾性分析接受超声弹性、二维及彩色多普勒检查的193例乳腺肿块患者资料,探讨超声弹性成像技术在乳腺肿块良恶性鉴别诊断中的临床应用价值,现报道如下.
