摘　　要：目的:探讨色素沉着绒毛结节性滑膜炎(PVNS)的影像学表现。方法:回顾性分析14例经手术及病理证实的PVNS患者的X线平片、CT、MRI等影像学资料。结果:14例X线检查者均见关节囊肿胀,其中8例骨质受侵蚀,1例可见软组织肿块。8例CT检查均示关节囊肿胀,其中6例可见关节腔积液及周围骨质受侵蚀,2例见软组织肿块影,2例增强扫描者均可见强化的滑膜结节和增厚的滑膜。10例MR检查者弥漫型8例,局限型2例,均可见到关节囊肿胀及数量不等的增生滑膜绒毛结节,其中9例在增生滑膜内可见含铁血黄素沉着,呈长T1、短T2低信号,8例关节腔积液及骨质受侵蚀,3例见软组织肿块,3例增强扫描者示增厚的滑膜和结节明显强化。结论:MRI对色素沉着绒毛结节性滑膜炎诊断及鉴别诊断具有重要价值,是一种简单、无创、有效的检查手段。Objective：To evaluate the image findings of pigmented villonodular synovitis. Methods： X-ray, CT and MR fingings in 14 cases with PVNS were analyzed retrospectively. Results： X-ray of the 14 patients could show swelling of the joint. Bony erosion were shown in 8 cases. One patient had soft tissue mass CT scan showed the joint swelling presented in all of the 8 patients; 6 patients showed the joint effusion and bony erosion; 2 patients had the soft tissue mass. The proliferated synovium and synoium nodules were enhanced after contrast administration in 2 patients. MRI showed the joint swelling and thickened synovium in all of the 10 patients. Diffuse patten was seen in 8 cases and localized patten was seen other 2 cases. Hemosiderin deposition in the 9 thickened synovium was revealed as a low signal on both T1WI and T2WI; 8 patients had the joint effusion and bony erosion; 3 patients had the soft tissue mass. The proliferated synovium and synovium nodules were enhanced after contrast administration in 3 patients. Conclusion. MRI has important value in diagnosis and differencial diagnosis of pigmented villonodular synovitis. It should be a simple, non-invasively, effective diagnostic method.
