摘　　要：目的:探讨软骨母细胞型骨肉瘤的X线片、CT及MRI影像学表现和病理基础的相关性。方法:回顾性分析12例经病理证实的软骨母细胞型骨肉瘤X线片、CT及MRI片资料,并与病理结果结合分析。结果:软骨母细胞型骨肉瘤的影像学表现包括肿瘤骨、瘤软骨钙化、骨膜反应及软组织肿块。软骨母细胞型骨肉瘤的间隔强化和边缘强化区代表肿瘤的纯软骨成分。MRI增强扫描有利于软骨母细胞型骨肉瘤与软骨肉瘤的鉴别。结论:软骨母细胞型骨肉瘤容易误诊为软骨肉瘤,合理应用X线、CT、MRI检查,可提高软骨母细胞型骨肉瘤与软骨肉瘤鉴别诊断的准确性。Objective：To explore the imaging features on X ray,CT and MRI in 12 cases of chondroblastic osteosarco ma correlated with pathologic results. Methods：X-ray,CT and MRI findings in 12 patients with pathologically-proved chon droblastic osteosarcoma were retrospectively analyzed and then were studied in relation to the pathological findings. Results： The imaging manifestations of chondroblastic osteosarcoma included neoplastic bone, tumorous calcifications, periosteal re action and soft tissue mass. In chondroblastic osteosareoma septal and peripheral rim enhancement represented tumour with a pure chondroid matrix. Enhanced MRI scans were advantageous in differentiating between chondroblastic osteosarcoma and chondrosarcoma. Conclusion： Since chondroblastic osteosareoma is easily misdiagnosed as other bone tumors such as chondrosarcoma,appropriate use of X-ray,CT and MRI can inprove the accuracy of diagnosis between chondroblastie osteosarcoma and chondrosarcoma.
