目的探讨滑膜骨软骨瘤病影像学表现。方法回顾性分析45例滑膜骨软骨瘤病患者的X线、CT和MRI的影像资料。结果 X线、CT和MRI均见游离体。游离体在X线和CT上表现高密度的钙化体,圆形或椭圆形,大小不一。MRI图像上游离体为T1WI呈低信号强度,T2WI可见其信号不均,钙化部分呈低信号,而未钙化部分呈中等或高信号强度改变。膝关节、髋关节为最易受累关节,占约75.56%。结论 X线诊断简便、快捷,CT、MRI可提供更多的信息。
Objective To investigate the imaging findings of synovial chondromatosis. Methods A retrospective analysis of 45 cases of synovial osteochondromatosis patients X-ray, CT and MRI image data. Results X-ray, CT and MRI were seen free. Free body X-ray and CT showed high-density calcification, round or oval, different sizes. MRI images of isolated T1WI showed low signal intensity, T2WI visible uneven signal, calcified part was low signal, and non-calcified part showed moderate or high signal intensity changes. Knee joint and hip joint are the most affected joints, accounting for about 75.56%. Conclusion X-ray diagnosis is simple and quick, and CT and MRI can provide more information.
