| 摘 要： | 目的探讨腱鞘巨细胞瘤(GCTTS)的MRI征象并与病理对照。方法收集我院经手术病理证实的13例GCTTS进行回顾性研究。男6例,女7例,年龄28～65岁,平均(42.5±10.1)岁。所有病例均行MRI平扫及增强检查。结果局灶型GCTTS 9例,病灶与腱鞘关系密切,位于手指5例,均呈≥180°包绕指骨,邻近骨皮质均不同程度侵蚀、吸收破坏,其中左手1例360°包绕拇指骨,邻近骨皮质均不同程度侵蚀、吸收破坏。弥漫型4例,病灶呈散在结节样或团块状分布于膝、踝关节腔及周围存在滑膜组织的间隙内。与邻近骨骼肌相比,T1WI上病灶呈等或稍低信号为主,右髌上囊内病灶大部分囊变且T1WI上囊液呈稍高信号。T2WI/PDWI上病灶信号复杂,内见低信号区。病灶实性部分不均质强化。镜下见较多单核组织细胞、多核巨细胞,并见散在泡沫细胞及含铁血黄素沉积。结论 GCTTS的MRI征象具有一定特征,是其病理改变的反映。
