目的探讨软骨母细胞瘤的X线、CT、MRI影像学特征及其诊断价值。方法回顾性分析经手术病理证实的22例软骨母细胞瘤的3种检查方法的影像学征象及差异性。结果 22例中17例行X线检查,15例行CT检查,11例行MRI扫描;X线、CT和MRI对钙化的检出率分别为47%、66.7%和54.5%;对硬化边的检出率分别为82.3%、80%、90%;骨膜反应检出率分别为17.6%、13.3%和18.2%;MRI骨髓水肿的检出率为72.7%。结论软骨母细胞瘤的影像学表现有一定的特征性,联合运用不同的检查手段能更全面地显示软骨母细胞瘤的影像学特点,有助于正确诊断。
Objective To investigate the imaging features and diagnostic value of X-ray, CT, MRI of chondroblastic tumor. Methods We retrospectively analyzed the imaging features and differences of three kinds of examination methods of 22 cases of chondroblastoma confirmed by surgery and pathology. Results Of the 22 cases, X-ray examination was performed in 17 cases, CT scan was performed in 15 cases and MRI scan was performed in 11 cases. The detection rates of calcification by X-ray, CT and MRI were 47%, 66.7% and 54.5% respectively. The detection rates were 82.3%, 80% and 90% respectively. The detection rates of periosteal reaction were 17.6%, 13.3% and 18.2% respectively. The detection rate of MRI bone marrow edema was 72.7%. Conclusion The imaging findings of chondroblastoma have certain characteristics. Combined use of different examination methods can display the imaging features of chondroblastoma more comprehensively and help to diagnose correctly.
