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-ray and CT findings of synovial osteochondromatosis and to discuss the value of CT in the diagnosis of this disease. Methods 11 cases of pathologically confirmed synovial osteochondromatosis patients underwent CT scan, including 8 cases of radiography. Results The correct diagnosis of X-ray 6 cases, CT correct diagnosis of 10 cases. 11 cases of CT scan showed calcification or ossification of the free body and the pituitary, as well as different degrees of effusion within the joint, 9 cases of synovial thickening and showed localized villous or nodular uplift. Free body and pituitary morphology varied, uniform or uneven calcification, the number from a few to hundreds. Conclusion CT can clearly diagnose the disease, can find signs of X-ray can not be found, with high diagnostic value.
