目的 探讨滑膜软骨瘤病的MR影像表现,评价MR对滑膜软骨瘤病的诊断价值.方法 回顾性分析16例经病理证实的滑膜软骨瘤病患者的影像资料,所有患者均行X线平片、MR平扫和增强检查.肩关节2例,髋关节4例,膝关节8例(2例为双膝关节),踝关节2例.结果 X线平片正确诊断11例(13个关节),表现为关节间隙内及关节周围多发大小相似或不等的高密度结节影,呈中心低周边高的同心圆状改变.MR正确诊断14例(16个关节),表现为滑膜结节样增厚、明显强化,关节内多发软骨性或骨性结节,结节表面可有强化,部分结节与滑膜相连,关节积液和关节退行性改变.MR可以显示X线平片不能显示的滑膜异常,有助于区分关节内游离体的性质,对病变细节的显示明显优于X线平片.结论 MR可以清晰显示滑膜病变和关节内游离体,对于滑膜软骨瘤病的诊断、范围的确定和明确游离体性质具有重要价值.
目的 探討滑膜軟骨瘤病的MR影像錶現,評價MR對滑膜軟骨瘤病的診斷價值.方法 迴顧性分析16例經病理證實的滑膜軟骨瘤病患者的影像資料,所有患者均行X線平片、MR平掃和增彊檢查.肩關節2例,髖關節4例,膝關節8例(2例為雙膝關節),踝關節2例.結果 X線平片正確診斷11例(13箇關節),錶現為關節間隙內及關節週圍多髮大小相似或不等的高密度結節影,呈中心低週邊高的同心圓狀改變.MR正確診斷14例(16箇關節),錶現為滑膜結節樣增厚、明顯彊化,關節內多髮軟骨性或骨性結節,結節錶麵可有彊化,部分結節與滑膜相連,關節積液和關節退行性改變.MR可以顯示X線平片不能顯示的滑膜異常,有助于區分關節內遊離體的性質,對病變細節的顯示明顯優于X線平片.結論 MR可以清晰顯示滑膜病變和關節內遊離體,對于滑膜軟骨瘤病的診斷、範圍的確定和明確遊離體性質具有重要價值.

Objective To explore MR imaging features of synovial chondromatosis,and evaluate the diagnostic value of MR imaging.Methods The imaging data of 16 cases with pathologically confirmed synovial chondromatosis were analyzed retrospectively,who underwent the preoperative X-ray plain film and MR plain-scan and enhanced-scan.Two cases of should joint,4 cases of hip joint,8 cases of knee joint(ten joints),2 cases of ankle joint.Results Eleven cases (13 joints) were truly diagnosed according to X-ray plain film,the typical features of synovial chondromatosis were hyperdense free bodies in the joint space and adjacent soft tissue,which showed the concentric lamina sign.Fourteen cases (16 joints) were truly diagnosed according to MR imaging,which clearly showed thickened synovium with significant enhancement,multiple intraarticular cartilage or bony nodules with the surface enhanced,and some nodules connected with thickening synovial membrane,joint effusion and joint degeneration.MR could display the synovial abnormalities that could not be displayed in X-ray plain film,which was helpful to distinguish the characteristics of free bodies in joint,and superior to X-ray plain fdm in showing the lesions in detail.Conclusion MR could clearly show the synovial abnormalities and free body in the joints,which has important value for the diagnosis of synovial chondromatosis,determination of the extent of lesions and the characteristics of free body.
