摘要

目的：探讨膝关节色素沉着绒毛结节性滑膜炎（PVNS）的影像学表现与病理变化的关系。方法：对19例膝关节PVNS的MRI、超声及X线影像进行回顾性分析，并与手术病理结果对照。结果：19例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；滑膜增厚：MRI（19/19），超声（19/19），X线（0/19）；关节积液：MRI（19/19），超声（19/19），X线（6/19）；关节内软组织结节：MRI（19/19），超声（19/19），X线（11/19）；关节内脂肪垫受侵：MRI（12/19），超声及X线（0/19）；半月板及交叉韧带受累：MRI（9/19），超声（3/19），X线（0/19）；软骨或骨受侵：MRI（11/19），超声（3/19），X线（5/19）。结论：MRI较X线及超声更能敏感显示PVNS对关节内外组织结构的侵犯程度及范围，是诊断PVNS的理想检查方法。

Abstract

Objective: To study the imaging features and the pathologic changes of pigmented villonodular synovitis(PVNS) of the knee joint. Methods: MRI, ultrasonography and X-ray appearances in 19 cases with PVNS of the knee joint were studied retrospectively, and were compared with surgical and pathological findings. Results: Nineteen cases of PVNS were diffuse form. The fundamental pathological alteration is idiopathic proliferation of synovial tissue and deposition of hemosiderin within villondules; In all the cases, thickened synovium seen in MRI(19/19), ultrasonography(19/19), X-ray(0/19); knee joint effusion seen in MRI(19/19), ultrasonography(19/19), X-ray(6/19); soft tissue nodule in joint space seen in MRI(19/19), ultrasonography(19/19), X-ray(11/19); erosion of fat pad in joint space in MRI(12/19), ultrasonography(0/19), X-ray(0/19); destruction of meniscus and cruciate ligment seen in MRI(9/19), ultrasonography(3/19), X-ray(0/19); erosion of cartilage and bone seen in MRI(11/19), ultrasonography(3/19), X-ray(5/19). Conclusion: MRI is the perfect examination means for the PVNS.
