Conclusion Ultrasonography can act as a routine examination technique in the diagnosis of the PVNS .

结论超声检查在PVNS诊断中有较高的应用价值，可作为PVNS首选检查方法之一。

Results 15 of 17 cases of PVNS were diffuse forms and the other two cases were localized forms .

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；

In localized form of PVNS in 2 patients , the single mass with joint effusion occurred .

2例局灶型PVNS表现为单发性肿块伴关节腔积液。

The main radiologic features of PVNS included synovial swelling , bony erosion or / and cystic bony destruction .

其主要X线表现有滑膜肿胀，骨糜烂或/和囊状骨破坏。

Methods : Retrospective analysis was performed in 12 PVNS patients , and the clinical signs , radiological and pathological changes , and combined therapy were evaluated .

方法：对12例PVNS患者的诊断和治疗进行回顾性分析，对其临床体征、影像学及病理学检查特征、临床综合治疗等进行评价。

Objective : To explore the treatment technique of pigmented villonodular synovitis ( PVNS ) of the knee under arthroscopy and evaluate its results .

目的：探讨关节镜下诊治膝关节弥漫型色素沉着绒毛结节性滑膜炎的方法及疗效。

The group of patients of localized ( nodular ) PVNS improved from an average preoperative score of 5 . 40 points to an average postoperative 11.8 points .

局限性色素绒毛结节性滑膜炎术前平均（5.40±1.52）分，术后平均（11.80±0.45）分。

Purpose To research the pathogenesis and mechanism of bone erosion and the imaging characters of pigmented villonodular synovitis ( PVNS ) of the knee .

目的探讨膝关节色素沉着绒毛结节滑膜炎（PVNS）的发病与骨破坏机制、影像特征。

The surgical treatment of extensive diffuse pigmented villonodular synovitis ( PVNS ) of large joints alone is unsatisfactory , with high rates of local recurrence .

传统外科手术來治療色素沉著性绒毛膜关节炎因高局部復发率而不尽理想；

Objective : To evaluate the MRI representations of pigmented villonodular synovitis ( PVNS ) of the knee joint , and increase the recognition of the disease .

前言：目的：分析膝关节色素沉着绒毛结节性滑膜炎（PVNS）的MRI影像表现，提高对本病的认识。

Results : The clinical features of PVNS included articular engorgement and pain associated with hydrarthrosis , decreased signal intensity on both T1-and T2-weighted MRI , and rust-like staining in synovium .

结果：PVNS以膝关节肿痛伴有咖啡色关节积液、MRI检查（T1和T2加权像）滑膜的低密度信号、滑膜内含有铁锈样色素斑等改变为临床特征；

Effects of electrolytic lesion of the PVNs on the inhibition of cortically evoked jaw movement ( CEJM ) induced by stimulation of the central end of the cervical vagus nerve were studied in rabbits .
