摘　　要：目的:探讨超声及MRI对色素沉着绒毛结节性滑膜炎(PVNS)的表现。方法:回顾性分析27例PVNS的声像图、MRI特征及病理结果。结果:超声表现为滑膜增厚;并有绒毛突起突入腔内,部分融合呈结节状;伴有不同程度关节腔积液;增生滑膜和突起绒毛内可见丰富血流;部分病例绒毛向周围组织侵蚀性生长。MRI主要表现为滑膜不规则结节状增生或弥漫性增生,内含铁血黄素沉积,关节内外结构可受累。结论:超声及MRI对PVNS诊断有重要的临床价值,MRI优于超声检查,超声可作为PVNS的首选筛检方法。Objective.. To evaluate the value of ultrasonography and MRI in diagnosing pigmented villonodular synovitis （PVNS）. Methods ：A retrospective study in 27 cases of PVNS of the ultrasonographic、MRI and the results of pathology. Results：Ultrasound showed thickening of the synovial;Villus protruding into the cavity,part of them integrate into nodules,echo nodules were diversity;With varying degrees of joint effusion;Synovial hyperplasia and within the protuberant villus could be seen the pile-rich strip.star-like point of blood flow or a fire ball ;Some of the cases ,villus invasive growth to surrounding tissue ,along the muscle gap or spread of bone erosion. The main MRI showed irregular synovial hyperplasia,or diffuse nodular hyperplasia,hyperplasia of synovial and nodules include hemosiderin,inside and outside the structure of the joint could be corroded. Conclusion ..Ultrasonography and MRI of PVNS diagnosis has an important clinical value,MRI is superior to ultrasonography,ultrasonography can be used as the first screening method of choice for PVNS.
