色素沉着绒毛结节性滑膜炎的彩超声像图表现

Sonographic features of pigmented villonodular synovitis

目的探讨色素沉着绒毛结节性滑膜炎高频声像图的特点。方法应用高频超声观察9例色素沉着绒毛结节性滑膜炎,并将声像图与手术、病理结果对照。结果 9例患者病变部位均见滑膜不同程度的增厚,呈弥漫分布的结节状隆起或形态不规则的实质性团块,其中6例增厚的滑膜见较丰富血流信号。结论色素沉着绒毛结节性滑膜炎超声表现具有一定的特征性,但最终诊断仍依赖活检或手术。

Objective To explore the high-frequency sonographic features of pigmented villonodular synovitis （PVNS）. Methods High-frequency ultrasound were applied to observing 9 patients with pigmented viUonochlar synovitls, and thier ultrasound images were contrasted to the results of surgery and pathology. Results The synovium in the pathological changing parts in 9 patients could be seen thickening in varying degrees, showing diffuse tuberous lumps or forming substantial masses of irregular shapes. Among these patients, 6 patients were observed rich blood flow signals in the thickening synovium. Conclusion Sonographic manifestation of pigmented villonodular synovitis has certain features, yet the final diagnosis shall rely on biopsy or surgery.
