目的探讨关节滑膜骨软骨瘤病的影像学表现及鉴别要点。材料与方法回顾性分析15例关节滑膜骨软骨瘤病患者的X线、CT和MRI的影像资料。结果15例中11例经手术病理证实，4例关节镜证实。X线、CT和MRI均可见游离体形成。游离体体在X线和CT上表现为高密度的钙化小体，圆形或椭圆形，大小不一。小结节影在MR T1WI呈低信号，在T2WI信号不均，钙化部分呈低信号，而未钙化部分呈中等或高信号。CT检查可以发现隐蔽游离体、增厚的滑膜和关节腔积液。MRI能发现关节内未钙化的游离体，除可见关节游离体外，还清晰显示软骨、滑膜、周围软组织的改变和关节积液等表现。结论游离体是滑膜骨软骨瘤病的特征性影像表现，是影像诊断的主要依据，X线诊断简便、快捷，CT、MRI可提供更多的信息。

Objective:To evaluate the image ifndings of synovial osteochondromatosis and differential diagnosis. Materials and Methods:X-ray, CT and MRI ifndings in 15 cases with synovial osteochondromatosis were analyzed retrospectively. Results:11 cases of 15 cases were proved by clinical and pathologically, 4 cases of 15 cases were proved by arthroendoscopy. X-ray, CT and MRI can ifnd small loose body, X-ray and CT can find high densidy calcification round and oval shape, large or small of small loose body. MRI can ifnd small cartilage nodular had hypointensity on T1WI, had a mixture of hypo-hypeintensity on T2WI. CT examination can be found hidden loose bodies, thickened synovium and intra-articular effusion MR can detect intra-articular not free of calciifcation cartilage tumor nodules, in addition to articular loose bodies can be seen, but also clearly indicated that cartilage synovial soft tissue changes and joint effusion. Conclusions:Loose body is the characteristic features in imaging. X-ray diagnosing simple and high-speed, CT and MRI can ifnd more information.
