摘要
目的:探讨二维及彩色多普勒超声对平滑肌肉瘤(LMS)的诊断价值。方法:收集我院2005-2014年间经手术病理证实为LMS的患者58例,回顾性分析患者的临床及超声图像资料。结果:共收集患者58例(共分析61个病灶),男性21例,女性37例,平均年龄(51.7±13.3)岁,61个病灶中分布于腹腔及腹膜后的有45个,躯干及四肢13个,下腔及股总静脉3个;所有病人超声均发现病灶,发现率为100%,超声定位准确率95%;肿瘤平均大小(8.6±5.8)cm,低弱回声52个(85.2%),边界较清楚45个(73.8%),形态不规则36个(59.0%),内部回声不均匀31个(50.8%),伴液化13个(21.3%),钙化4个(6.6%)。血流分级:0级15个(24.6%),1-2级38个(62.3%),3级8个(13.1%);超声提示肿瘤包绕或压迫邻近器官20例;提示对周围组织侵犯13例,超声与CT/MRI相比,两组病变发现率、定位准确率、提示包绕压迫征象及浸润征象率的差异无统计学意义(P〉0.05)。结论:LMS好发于中老年,腹膜后多见,超声多表现为较大体积的低弱回声团块,边界较清,内部可见点线状血流信号,超声对LMS的发现率、定位准确率高,并能提示肿瘤对周围组织的压迫或浸润。
Objective: To investigate the value of two-dimensional and color doppler ultrasound in the diagnosis of leiomyosarcoma (LMS). Methods: Clinical data and ultrasonic findings of 58 patients with histopatholgieally proved LMS in our hospital between 2005-2014 were analyzed retrospectively. Results: Among 58 patients (61 lesions were analyzed) , 21 were male and 37 were female, with an average age of 51.7 ± 13.3 years old. Forty-five masses located at the peritoneal cavity and retroperitoneal space, 13 located at trunk and limbs and 3 located at the spaces of inferior vena cava and femoral vein. Ultrasound could find all of the lesions, and the location accuracy by ultrasound reached 95 %. The mean diameter of masses was ( 8.6 ± 5.8 ) era. Fifty-two masses ( 85.2% ) presented as low or weak echo on ultrasonography. Forty-five masses (73.8%) had clear borders and 36 masses( 59.0% ) had irregular shapes. Thirty-one masses( 50.8% ) were found with inhomogenous internal echo, liquefaction was seen in 13 masses(21.3% ) ,while calcification was noticed in 4 cases(6.6% ). Color Doppler flow signals of these masses were 0 grade ( n = 15 ) , 1 and 2 grade ( n = 38 ) , and 3 grade ( n = 8 ). Masses in 20 patients were observed surrounded with or having compassion on adjacent organs and in 13 patients were observed infiltrating adjacent organs. Comparing ultrasound and CT/MRI, there was no statistically significant difference between the rate of finding the abnormal, locating the lesions, and prompting compression and infiltration signs in the group. Conclusion : LMS is commonly found in middle-aged and older people. Sonographically these soft tissue masses tend to locate at retroperitoneal space, be large, have weak echo and clear boundary, have dotted or linear blood flow signal internally. Moreover, ultrasound can reach a relatively high accuracy of detection and location, and it can detect the compression and infiltration of the adjacent tissues or organs.
