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，提高对本病的诊断水平。方法：对经手术和病理证实的12例色素沉着绒毛结节性滑膜炎的影像学资料进行回顾性分析。X线平片检查9例，CT检查4例，MRI检查5例。结果：12例患者共有12个病灶。全部病例均有关节肿胀，3例有钙化。关节间隙7例正常，1例增宽，4例狭窄；关节骨质侵蚀破坏5例，周围均见硬化缘。CT检查的4例PVNS全部为弥漫型，均可见关节腔积液。MRI检查的5例中弥漫型4例，均见关节腔积液及不规则增厚的低信号滑膜；局灶型1例，表现为单发性肿块伴关节腔积液。结论：PVNS的MRI表现较X线平片、CT具有特征性，有助于诊断及鉴别诊断；钙化不宜作为否定PVNS的依据。
Abstract
Objective: To evaluate the imaging features of pigmented villonodular synovitis(PVNS), and improve imaging diagnostic ability of the disease. Methods: The imaging findings of 12 cases with PVNS confirmed by operation and pathology were analyzed retrospectively. Plain film was performed in 9, CT in 4, MRI in 5. Results: There were totally 12 lesions. Swelling of joint was seen in all patients, and 3 cases with calcifications. In total 12 patients, joint space was normal in 7 cases, widened in 1 case, narrow in 4 cases; and bone erosion was seen in 5 patients, the sclerotic margins were presented in all lesions. CT scan showed diffuse form and joint effusion in all of the 4 patients. MRI in 5 patients showed diffuse form(4 cases) and localized form(1 case); in diffuse form of PVNS, joint effusion was present, and low signal proliferated synovium in all of the patients; in localized form of PVNS in 1 patient, the single mass with joint effusion occurred. Conclusion: The MRI findings of PVNS is characteristic, which is of specific value in the diagnosis and differential diagnosis. Calcifications should not be taken as a denial of PVNS.
