摘要
目的探讨色素沉着绒毛结节性滑膜炎（PVNS）的超声表现与病理变化的关系。方法17例PVNS患者均经手术和病理证实，对超声表现和病理进行对比分析。结果17例PVNS，15例弥漫型，2例局限型，弥漫型超声特点：①不同程度关节腔积液；②均见滑膜增厚并有绒毛突起突入腔内，呈“溶洞征”，部分融合呈结节状，结节回声呈多样性；③增生滑膜和突起绒毛内可见丰富条状、星点状血流或火球状血流，是本病特征；④部分病例绒毛向周围组织侵蚀性生长，沿肌肉间隙蔓延或侵蚀骨质。局限型超声表现仅为低回声团块，无关节腔积液。结论超声检查在PVNS诊断中有极高应用价值的影像学方法。
Objective To study the ultrasonographic apprearance of pigmented villonoduler synovitis （PVNS） and its pathologic changes. Methods To evaluate and compare the ultrasound findings and pathologic changes in 17 cases with PVNS which were proved by the surgical finds and pathologic studies. Results 15 of 17 cases of PVNS were diffuse forms and the other two cases were localized forms. In the cases of diffuse form, we found arthroedema and thickness membrana synovialis and villonodular protuberance. heterogeneous echo. Sonograms revealed extensive blood signals in thickened membrana synovialis and villonodular protuberance reagarded as its characteristic appearance. In some cases, villonodular protuberance In localized type PVNS was mainly demonstrated as the nodulated and hypoechoic proliferation of synovium, however, no hydrarthrosis of the joint found. Conlusions Ultrasonography is a valuable imaging method in the diagnosis of the PVNS.
