目的 分析转移性骨肿瘤漏、误诊的原因 ,提高对该病影像诊断水平。材料与方法 回顾分析资料完整的转移性骨肿瘤10 5例 ,其原发肿瘤主要为肺癌、前列腺癌、消化道癌及乳癌等。所有病例均摄X线平片 ,其中CT检查 3 1例 ,MR检查 2 1例 ,ECT检查 3 4例。结果 骨转移瘤以多发、溶骨型为主。初次影像检查漏、误诊分别为 :X线平片 3 5例 ,CT 5例 ,MR及ECT各 1例。结论 影像检查首选ECT和X线平片 ,有条件时最好作CT或MRI检查 ,并做必要的鉴别诊断。
Objective To analyze the causes of misdiagnosis and misdiagnosis of metastatic bone tumors and improve the diagnostic level of the disease. Materials and Methods A total of 105 cases of metastatic bone tumors were retrospectively analyzed. The primary tumors were mainly lung cancer, prostate cancer, gastrointestinal cancer, and breast cancer. X-rays were taken in all cases, including CT examination in 31 cases, MR examination in 21 cases, ECT examination in 34 cases. Results The bone metastasis was mainly composed of multiple and osteolytic bone types. Leakage and misdiagnosis of the initial imaging examination were as follows: 35 plain radiographs, 5 CTs, and 1 MR and ECT. Conclusion ECT and X-ray plain film are preferred for imaging examination. CT and MRI examinations are the best when conditions are available, and necessary differential diagnosis is made.
