摘要
目的探讨髋周骨内腱鞘囊肿的CT和MRI表现及其诊断价值。资料与方法回顾分析15例经手术病理证实的髋周骨内腱鞘囊肿CT、MRI资料。螺旋CT检查10例,MRI检查8例。3例同时做CT和MRI检查。结果15例共21个病灶,9例单发,6例多发,其中3例为双侧对称。19个病灶紧邻股骨头前上基底部承重关节面下,2个病灶位于髋臼顶。CT显示类圆形或不规则形囊样透亮区,边缘清楚,有完整、薄层硬化边,相邻关节间隙无改变。MRI显示病灶轮廓呈圆形或类圆形单囊状、花瓣形、多房囊状长T1、长T2信号,环以低信号硬化边。结论髋周骨内腱鞘囊肿在CT及MRI上具有特征性表现,可以做出正确诊断。CT检查对病灶细节显示清晰,可作为首选检查方法,MRI可以显示邻近关节软骨有无受累,对临床治疗有很大价值。
Objective To discuss the CT and MRI features of intraosseous ganglion cysts surrounding hip joint and their diagnostic value. Materials and Methods 15 cases of intraosseous ganglion cysts confirmed pathologically were reviewed retrospectively, 10 cases were performed with CT and 8 cases with MRI, 3 cases with both of them. Results There were 21 lesions in 15 cases, solitary lesions in 9 cases, multiple lesions in 6 cases （including bilateral symmetry in 3 cases）. CT showed that lesions had round or irregular cystic erosions with clear sclerosis edge, predominantly locating in superior-anterior load - bearing surface of femoral head, partly in the connective part of the roof. Lesions had hypointensity and hyperintensity signal with hypointensity rim on T1W and T2W respectively. Conclusion Itraosseous ganglion cysts have the characteristic features on CT and MRI. It is not difficult to make the correct diagnosis. Because of the advantage of scrutinizing details, CT is the first choice, and MRI can depict articular cartilage clearly.
