摘要
目的探讨髋臼邻关节骨囊肿的X线和CT、MRI表现及其诊断价值。方法回顾性总结我院1990年9月，2005年3月具有典型表现的5例髋臼邻关节骨囊肿，其中1例撮有X线、CT、MRI片，资料齐全。结果5例病人显示6个病灶。病灶呈圆形和类圆形，边界清楚，有薄层硬化缘。1例CT显示双侧囊肿均与髋关节相通；MRI表现为以液体信号为主，其内杂有不规则信号。结论X线检查简单易行，可作为髋臼邻关节骨囊肿的首选影像学检查方法。CT时病灶有更高的检出率，MRI可确定病变性质，能对多数病人做出诊断。应选择使用。结合发病年龄、病变部位、临床症状和影像学表现，对本病可以作出正确诊断。
Objective To study the X - ray,CT and MRI features of Juxta - articular bone cyst in the acetabulum and their diagnostic value. Methods Five cases with typical features were reviewed retrospectively, One of them had been examined by the X - ray radiography, CT and MRI. Results Six leisions were shown in the five cases with clear and sclerotic edges. One patient showed both Juxta- articular bone cysts in bilateral acetabulums communicating with hip joints on CT images, MRI showed liquid signal mixed with heterogeneous signals on T2 weighted images.Conclusion X - ray photography is simple and easy to perform and can be the first of choice of image examination for the disease. CT and MRI are more sensitive and valuable for most patients. Combining with patients＇ age, lesion distribution, clinical manifestations, and imaging features, it is possible to make a definate diagnosis of Juxta- articular bone cyst in the acetabulum.
