摘　　要：目的探讨慢性淋巴水肿相关的血管肉瘤(Stewart-Treves综合征,STS)的MR表现。方法回顾性分析5例经病理及手术证实的STS的临床及MRI表现。结果 STS的MR表现为在长期、显著淋巴水肿的肢体皮肤表面及皮下软组织内散在的软组织结节,大多数结节T1WI呈中等信号强度,T2WI上表现为肿胀增厚的软组织中的低信号结节,2例结节内混杂有稍长T2略高信号,1例中心区可见点状短T1低信号。2例可见肌肉组织受累。增强扫描显著强化。结论皮肤及皮下软组织内多发、大小不等的短T2信号软组织结节是STS较有特征性的MRI表现。STS的MR表现具有一定特征,临床病史结合MRI检查对于其定位及定性诊断有帮助。Objective To study the MR imaging features of Stewart-Treves syndrome（STS）. Methods The MR ima- ging and clinical feature of 5 cases with STS were analyzed retrospectively and correlated with operative and pathologic re- ports. Results All cases had long term and serious chronic lymphedema of upper extremities. MR features included mul- tiple soft tissue nodules scattered on the surface of the skin and in subcutaneous soft tissues, most of the lesions showed in- termediate signal on T1 WI and hypointensity signal on T2WI , with intense and uniform enhancement. 2 cases mixed with slightly hyperintense signal on T2WI and 1 case mixed with short Tl signal foci in the center. Muscle tissue involvement were observed in 2 cases. Conclusion The characteristics MR manifestation of STS is multiple short T2 signal nodules of various size scattered on the surface of the skin and in subcutaneous soft tissue .
