摘要
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 analyze the imaging features and diagnostic value of X-ray,CT and MRI in chondroblastoma.Methods The imaging findings including radiographs,CT and MRI of 22 chondroblastomas proven by surgery and pathology were retrospectively analyzed. Results Of all the 22 cases,17 cases had undergone raadiograph evaluation,15 cases had undergone CT examination,while 11 had undergone MRI examination. To determine the sensitivity of X-ray,CT and MRI in detecting calcifications,we compared the same with autopsy and X-ray,CT and MRI evaluation. The detectable rate of X-ray,CT and MRI was 47%,66. 7%,and 54% respectively; while the detectable rate of sclerotic rims diagnosed by X-ray,CT and MRI was 82. 3%,80% and 90%; the detectable rate of periosteal reaction was 17. 6%,13. 3% and18. 2%; the detectable rate of bone marrow edema diagnosed by MRI was 72. 7%. Conclusion Chondroblastoma has characteristic appearances in the plain radiograph,CT and MR images. It can be helpful to improve diagnostic accuracy by analyzing the X-ray,CT and MRI appearance comprehensively.
