【摘要】目的探讨X线与MRI对色素沉着绒毛结节性滑膜炎(PVNS的诊断价值。方法回顾性分析11例经手术病理证实的PVNS患者资料,7例发生于膝关节,4例发生于髋关节,分析其X线及MRI表现。结果11例患者的X线表现为关节囊肿胀、关节周围软组织肿块、关节边缘骨质缺损、关节面下囊性透亮区。MRI表现:弥漫型9例,结节型2例,表现为滑膜不同程度增厚、关节内软组织结节,T1WI及T2WI均呈低信号,FFE序列呈极低信号,并有不同程度的关节腔积液,5例发生骨或软骨的侵蚀。结论PVNS的X线表现无特征性,对本病的诊断仅能起到提示作用;MRI表现则有一定的特征性,对PVNS有定性诊断价值。【关键词】滑膜炎;色素沉着绒毛结节性;X线;磁共振成像X-rayandMRIevaluationofpigmentedvillonodularsynovitis
