目的 分析滑膜骨软骨瘤病的X线、CT表现 ,讨论本病的CT诊断价值。方法 11例经手术病理证实的滑膜骨软骨瘤病患者均行CT扫描 ,其中 8例摄X线平片。结果 X线正确诊断6例 ,CT正确诊断 10例。 11例CT扫描均见钙化或骨化的游离体与悬垂体 ,以及关节内不同程度积液 ,9例见滑膜增厚并呈局部绒毛状或结节状隆起。游离体与悬垂体形态多样 ,呈均匀或不均匀钙化 ,数目从几枚到上百枚。结论 CT可以明确诊断该病 ,能发现X线平片不能发现的征象 ,具有较高的诊断价值。
Objective To analyze the X-ra y and CT features of synovial osteocho ndromatosis and discuss the CT diagnostic value. Methods CT sca nning was perfor med in 11 cases with clinically and pathologically proved synovial osteochondrom atosis, of which 8 cases underwent X-ray film. The clinical and imaging feature s were analyzed and compared with the pathological findings. Results The knee jo int was mostly involved in synovial osteochondromatosis (55%). The loose and pen dulous bodies of the calcification and ossification were showed in 11 cases. The synovial showed villous and tubercular hyperplasia in 9 cases. The imaging feat ures of the intr_joint hydrops were showed in 11 cases. The amount of the loos e and pendulous bodies was from a few to hundred, the size and the calcification degree of the loose and pendulous bodies were closely related to the time of the ir formation and the course of synovial osteochondromatosis. Conclusion The loo se and pendulous bodies of the calcification and ossification are the X-ray and CT diagnostic basis in synovial osteochondromatosis. The diagnosis of typical sy novial osteochondromatosis can be made with CT. CT can find more indication than X-ray and can help make differential diagnosis.
