肺内良性结节性病变影像学误诊原因分析

Analyzing the Cause of Imaging Misdiagnosis in Benign Nodule Lesions of the Lung

目的 为了探讨肺内良性结节性病变影像学诊断中误诊原因。方法 回顾性分析 2 8例肺内良性结节性病变的影像学资料、X线平片加体层摄影 1 1例。CT平扫检查 1 7例 ,其中 8例采用增强扫描检查。结果 2 0例误诊为肺癌 ,余 8例中定性有误 ,其中错构瘤误诊为炎性假瘤 6例 ,炎性假瘤误诊为结核球 1例 ,错构瘤 1例。结论 重视临床病史 ,合理使用影像学检查方法 ,提高增强CT扫描检查的认识 ,加强影像学表现综合分析 ,是减少误诊的关键。

Purpose To analyze the cause of imaging misdiagnosis in benign nodule lesions of the lung. Methods The imaging data of 28 cases of benign nodule lesion of the lung were retrospectively analyzed. That includes 11 cases of X ray plain film and tomography, 17 cases of plain CT and 8 cases with contrast enhancement. Results 20 cases of benign nodule lesion were misdiagnosed to carcinoma. Other 8 cases could not make their diagnosis exactly. 6 cases of hamartomas were misdiagnosed to inflammatory pseudotumor. One case of inflammatory pseudotumor was diagnosed to tuberculoma, and another to hamartomas. Conclusion The key points in reducing the misdiagnosis rate are following, paying attention to the clinical history, reasonable using the imaging methods, expanding the knowledge of contrast enhanced CT scan, and strengthening the summarizing analysis of the imaging findings.
