CT误诊外围型肺癌20例分析
Analysis of CT Misdiagnosis in Twenty Patients with Peripheral Cancer of Lung.
【摘要】 文章对20例经手术病理证实为CT误诊病例进行了分析。认为误诊原因为:1.窗口技术不适当、对肺癌的征象判断不准确;2.忽视综合分析为诊断原则;3.对形态不典型的外围型肺癌认识不足。作者认为易导致误诊的是早期外围型肺癌;与肺结核并存的肺癌;类似机化性肺炎或肺良性肿瘤的肺癌;不按肺癌倍增时间生长的肺癌。文中重点讨论了外围型肺癌与肺结核和慢性肺炎的鉴别诊断。作者强调外围型肺癌的各种CT征象中无一项具有特异性诊断价值,提高肺癌诊断准确率的关键仍是影象所见结合临床、具体分析、综合诊断。
【Abstract】 The Paper analyzed the misdiagnostic causes by CT Proved pathologically after the operation in twenty Patients with peripheral cancer of lung. The cause which easyly result in misdiagnosis were considered as below:- Due to anapt window technique so that the signs of pulmonary cancer can’ t be accuratery identifyed.- Due to ignore the overall analysis as a diagnostic principle so that to be misdiagnosed- Due to the recognization of morphologically atypical peripheral cancer of lung to be insufficientThe authors considere the causes from pulmonary cancer itself resulting in misdiagnosis mainly were:- Peripheral cancer of lung to be early term;- Pulmonary cancer complicated with tuberculosis;- Pulmonary cancer to be similar to polarized Pulmonia or benign tumor in lung; ,- Pulmonary cancer growing independent of the multiplicative time which is specific for pulmonary cancer.The paper discussed emphatically the differential diagnosis between peripheral cancer of lung and tuberculosis and/or chronic pulmonia. The authors emphasize that there was not any specific diagnostic value in various CT signs, therefore. the critical factors influencing diagnostic accuracy remain necessary for CT imaging findings to be combined with clinical manifestations, and perform the practical analysis so that to obtain the accrurate diag-
