摘　　要：目的探讨肌间脂肪瘤的高频彩超特征。方法对18例肌间脂肪瘤的高频彩超图像进行回顾性分析。结果 18例中,其中位于下肢5例,上肢3例,颈部3例,肩背部2例,腰背部5例;类圆形1例、椭圆形12例、不规则形5例;5例边界清楚,7例边界部分清楚,6例边界不清楚。对比局部肌肉回声,高回声11例,低回声3例,等回声1例,混合回声3例。8例检出血流信号,均位于肿块周围,4例为静脉血流信号。结论肌间脂肪瘤具有相对特征性的声图像表现,高频彩超可准确判断肿物的位置、深度,具有较大的诊断价值。Objective To summarize the ultrasonographic features of intramuscular lipoma. Methods The ultrasonographic findings in 18 patients with intramuscular lipoma were retrospectively analyzed. Results of 18 cases, the masses located in the lower extremity in 5 cases, upper extremity in 3 cases, neck in 3 cases, shoulder and neck in 2 cases, and lumbus in 5 cases. Lesions were round in 1 case, oval in 12 cases and irregular in 5 cases. Masses were well-defined in 5 cases,partial well-defined in 7 cases and ill-defined in 6 cases. Overall lesion echogenicity was hyperechoic to muscle in 11 cases, hypoechoic to muscle in 3 cases,isoechoic to muscle in 1 cases and mix echoic to muscle in 3 cases. Color Doppler Flow hnaging （CDFI） showed blood flow signal around the masses in 8 cases and 4 were venous blood flow signal. Conclusion Intramuscular lipomas have some distinctive uhrasonographic features. Color Doppler ultrasound and could correctly show the location and deepness of the masses, which is useful for the diagnosis of intramuscular lipoma.
