Abstract:

目的:分析少见部位软组织黏液样纤维瘤(CMF)的CT及MRI表现,探讨CMF少见部位及其影像学特征。方法:回顾性分析7例经手术病理确诊的少见部位CMF影像学资料,7例均行CT检查,其中4例行MRI检查。结果:7例中,发生在长骨骨骺4例(胫骨近远端骨骺各1例,股骨近端骨骺1例,腓骨近端骨骺1例);扁骨2例;短骨1例。1 CT表现:膨胀性骨质破坏5例;偏心性骨质破坏4例;硬化边5例;粗细不均骨嵴或骨性间隔4例;7例均未见钙化或软组织肿块。2MRI表现:2例为T1WI低信号,2例为T1WI等信号,4例均表现为T2WI及T2WI抑脂高信号为主混杂信号。结论:CMF三种组织成分在CT和MRI上具有一定特征,可发生在长骨骨骺、扁骨、短骨等少见部位
