摘    要:目的:探讨MRI对四肢肌间海绵状血管瘤的诊断价值。方法:经手术病理证实的四肢肌间海绵状血管瘤13例,术前行MRSET1WI、T2WI及动态增强扫描。回顾性分析其MRI表现并总结其特征。结果:13例中3例肿瘤位于上肢,10例位于下肢,其中有4例位于膝关节附近。12例表现为单发的团块状病灶,1例为多个病灶。病灶大小不等,最长径1.5~20.1cm。T2WI上瘤灶呈均匀或混杂高信号;T1WI上5例呈低信号,5例呈等信号,3例呈稍高信号。增强扫描示病灶呈不均匀明显强化。近关节者与远离关节者表现有较大差异,1例位于膝关节附近者导致膝关节广泛受损,另1例位于腘窝者导致邻近软骨组织增生并致膝关节挛缩畸形,余11例无周围组织明显受累征象。结论:四肢肌间海绵状血管瘤的MRI表现有一定特征性,结合临床症状及体征,可对其做出定位及定性诊断。

Abstract:Objective:To investigate the MRI features for intermuscular cavernous hemangioma of extremities.Methods:13 cases of surgically and pathologically confirmed intermuscular cavernous hemangioma of extremities with pre-operative MR SE T1WI,T2WI and enhancement scans were reviewed and analyzed for the characteristic features retrospectively.Results:Of the 13 cases,3 occurred in upper extremities,and 10 in lower extremities,with 4 nearby the knee joint.12 cases showed as a single intermuscular mass and the other ...
