| 摘 要： | 目的：探讨膝关节色素沉着绒毛结节性滑膜炎（PVNS）的MRI表现与病理变化的关系。方法：对20例膝关节PVNS的MRI影像进行回顾性分析,并与手术病理结果对照。结果：20例膝关节PVNS均为弥漫型,病理特征为滑膜增厚呈结节状或绒毛状,有丰富的血管和大量含铁血黄素沉着。MRI表现均有滑膜增厚、关节内软组织结节,T1WI呈等或低信号,T2WI呈低信号;均有不同程度关节积液;关节内脂肪垫受侵15例;半月板及交叉韧带受累10例;软骨或骨受侵16例。结论：MRI对膝关节PVNS有特征性表现,并敏感显示关节内外组织结构的侵犯程度及范围,MRI是诊断PVNS的理想检查方法。

| Abstract: | Objective:To study the correlation of MRI features and pathologic changes of pigmented villonodular synovitis(PVNS) of knee joint.Methods:MRI of knee joint in 20 cases with PVNS were studied retrospectively,and correlated with surgical and pathological findings.Results:All of the twenty cases with PVNS were diffuse type.The basic pathological changes were nodular or villous proliferation of synovial tissue;with massive hemosiderin deposition and abundant blood vessels.The MRI manifestations were thickened s... |
