【摘要】 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28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11例,CT平扫检查17例,其中8例采用增强扫描检查。结果:20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。更多还原

【Abstract】 Objective: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.更多还原
