目的 探讨彩色多普勒超声在诊断大腿肌层肿块中的应用价值.方法 将30例大腿肌层肿块的超声表现与病理结果比对,进行回顾性分析.结果 大腿肌层肿块中恶性肿瘤8例(26.7％),包含黏液性纤维肉瘤、黏液性脂肪肉瘤、腺泡状软组织肉瘤、未分化多形性纤维组织细胞瘤和恶性孤立性纤维性肿瘤;良性肿瘤18例(60.0％),包含脂肪瘤、神经鞘瘤、血管瘤、血管脂肪瘤和黏液瘤;肿瘤样病变4例(13.3％),包含肌肉脓肿、骨化性肌炎、结节性筋膜炎.超声诊断大腿肌层肿块的总符合率为53.3％ (16/30),其中,良性肿瘤符合率(72.2％),高于恶性肿瘤符合率(12.5％)及肿瘤样病变符合率(50％).结论 大腿肌层良恶性肿瘤及肿瘤样病变的超声声像图有一定特征,能够为临床诊治提供有价值的参考.
<正>子宫肌瘤是女性生殖器官最常见的良性肿瘤,发生率为20%～30%[1,2]。子宫浆膜下肌瘤是其中一种,超声是其首选检查方法,一般不难诊断。当浆膜下肌瘤的蒂过长使之与子宫完全分离时则难以与卵巢肿瘤或盆腹腔其他来源肿块相
Objective To study the patent paraumbilical veins and abdominal varicose veins in portal hypertension by color Doppler ultrasound,and to establish the classification of portal hypertension.Methods Three groups of patients with portal hypertension,including 86 cases of liver cirrhosis,13 cases of Budd-Chiari syndrome and 6 cases of portal vein trunk or splenic vein thrombosis were examined by color Doppler ultrasound,abdominal varicose veins of portacaval collateral circulation and blood flow direction were observed.Results In liver cirrhosis group,the blood flow direction of abdominal varicose veins was towards the head above the navel,while towards the feet below the navel.In Budd-Chiari syndrome combined with IVC obstruction group,blood flow direction was toward the upper chest area.In portal trunk or splenic vein thrombosis group,the patent umbilical vein and abdominal varicose veins weren't seen.Conclusion Determination of patent paraumbilical veins and abdominal varicose veins by ultrasound can help to identify the location,degree and scope of vascular occlusion,which provids efective method for classification of portal hypertension and has significance for formulation of reasonable treatment plan.
胎儿泌尿系畸形是常见的一种先天性畸形,发生率为1/600～1/800[1],而胎儿泌尿道扩张占胎儿泌尿系畸形相当比率,有的出生后需手术治疗,有的影响双肾功能愈后极差.正确认识胎儿泌尿道扩张声像表现,对临床产前咨询、愈后评估、是否终止妊娠将提供有力依据.本文总结了14例胎儿异常泌尿道扩张产前超声表现,现报道如下.
Purpose:This article describes the ways by which thyroid diseases are examined,and shows the different features of these diseases on conventional ultrasound and Colour Doppler Flow Imaging.In addition,the differentiations between benign and malignant lesions are given.The characteristic imaging of metastases in the jugular lymph nodes is included.
