摘要 目的:探讨色素沉着绒毛结节性滑膜炎(PVNS)影像学表现。方法:回顾分析21例经手术病理证实的PVNS影像学资料,其中16例行X线检查,4例行CT平扫,13例行MRI平扫,2例行MRI增强扫描。结果:16例行X线检查者无异常发现4例,有异常发现12例;X线、CT表现关节周围软组织肿胀或肿块,关节间隙变窄或正常,骨质破坏周围可见硬化。13例行MRI检查者表现为弥散型11例,局灶型2例。增生的滑膜组织于T1WI上呈低信号或等信号,T2WI上呈低信号为主低高混杂信号,13例均可见多少不一的关节积液,9例可见关节软骨及软骨下骨质破坏。结论:PVNS的MRI表现较CT、X线表现具有特征性,MRI在PVNS的诊断与鉴别诊断方面具有重要价值。
