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 histopatholgically 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 perito-neal 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 di-ameter of masses was (8.6 ±5.8)cm.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 pa-tients 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 mas-ses 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.
