目的：借鉴误诊病例的经验教训，提高骨肿瘤的ＣＴ诊断水平。材料与方法：回顾性分析６５例经手术病理证实ＣＴ误诊的骨肿瘤或瘤样病变。结果：ＣＴ误诊的原因：（１）检查方法不当；（２）缺乏扎实的基础知识；（３）缺乏经验或对较少见骨肿瘤缺乏认识；（４）忽视对有诊断价值的ＣＴ征象认识；（５）ＣＴ的限度；（６）忽视局部骨肿瘤与周身性疾病或其他疾病的联系。结论：ＣＴ是诊断骨肿瘤或瘤样病变的重要手段，但有一定限度；学习掌握本专业及其相关的知识和技能、遵循正确的诊断思维方法、积累诊断经验是减少ＣＴ误诊的关键
Objective: To use the lessons learned from misdiagnosis cases to improve the CT diagnosis of bone tumors. Materials and Methods: A retrospective analysis of 65 cases of bone tumors or tumor-like lesions confirmed by pathology confirmed by CT. RESULTS: The reasons for CT misdiagnosis: (1) inadequate examination methods; (2) lack of solid basic knowledge; (3) lack of experience or lack of understanding of rare bone tumors; (4) neglect of recognition of diagnostic CT signs (5) Limitations of CT; (6) Ignoring the connection between local bone tumors and whole body disease or other diseases. Conclusion: CT is an important method for diagnosing bone tumors or tumor-like lesions, but it has a certain limit. Learning to master this specialty and its related knowledge and skills, follow correct diagnostic thinking methods, and accumulate diagnostic experience are the key to reduce CT misdiagnosis.
