【摘要】 目的 探讨滑膜软骨瘤的影像学特征。方法 回顾分析63例经手术病理证实的滑膜软骨瘤影像学资料,总结其X线平片(63例)、CT(12例)和MRI(18例)表现特征。结果 63例中发生在膝关节46例,髋关节12例,肘关节3例,踝关节1例,肩关节1例。X线平片显示59例关节周围软组织内多发且数量不等的结节状或不规则钙化骨化影.4例仅见关节软组织肿胀而未见钙化骨化影。CT均可见较平片更为清晰的多发的钙化骨化结节影及滑膜增厚。MRI均显示关节滑膜增厚及结节样隆起,并见1个或多个不同成分特征及信号强度的软骨小体。结论 滑膜软骨瘤病在X线平片、CT和MRI表现具有特征性,特别是MRI能发现病变早期未钙化的软骨小体,使该病在早期能作出正确诊断,同时MRI能对该病进行较准确的分型。更多还原

【Abstract】 Objective To discuss imaging(X-ray,CT and MRI) features of synovial chondromatosis.Methods X-ray(n=63),CT(n=12) and MRI(n=18) findings of 63 cases with synovial chondromatosis proved by pathology were retrospectively analyzed.Results The lesions located in knee joint(n=46), hip joint(n=12), elbow joint(n=3),ankle joint(n=1) and shoulder joint(n=1).X-ray showed multiple calcifications or ossifications with typical ring or irregular shape in soft tissues around the joints in 59cases and 4 cases with soft tissue swelling but no calcifications.CT showed the intra-articular calcifications more clearly and thickened synovial membrane.MRI revealed all the synovial thickening and one or more chondral bodies with different component and signal intensity.Conclusion Synovial chondromatosis has characteristic imaging features.Specially,MRI can reveal the chondral bodies which with calcification or not,MRI is of significant value in diagnosis early and classification of this disease.更多还原
