Analysis of the causes of misdiagnosis on CT films of 45 patients with lung cancer

目的 分析肺癌的CT误诊原因.方法 回顾性分析45例肺癌CT误诊病例,并与CT误诊为肺癌的肺结核26例及肺炎15例进行对照.结果 45肺癌误诊为肺结核19例,肺炎14例,肺脓肿4例,误诊为正常及胸膜间皮瘤各2例,误诊为其他病变4例.误诊病例表现为肺叶肺段阴影者26例,肺内球形病灶或结节影者19例.CT误诊原因较复杂,归纳其主要因素,可分为下列三个方面:①漏诊2例(4.5%).漏诊主支气管内肿物1例,肋骨破坏1例.②缺乏经验及综合分析欠妥者24例(53.3%).③CT表现不典型者19例(42.2%).结论 对CT征象认识不准确及过分强调某些征象是误诊的主要原因.合理而仔细的检查,并结合临床表现全...

Summary:目的 分析肺癌的CT误诊原因.方法 回顾性分析45例肺癌CT误诊病例,并与CT误诊为肺癌的肺结核26例及肺炎15例进行对照.结果 45肺癌误诊为肺结核19例,肺炎14例,肺脓肿4例,误诊为正常及胸膜间皮瘤各2例,误诊为其他病变4例.误诊病例表现为肺叶肺段阴影者26例,肺内球形病灶或结节影者19例.CT误诊原因较复杂,归纳其主要因素,可分为下列三个方面:①漏诊2例(4.5%).漏诊主支气管内肿物1例,肋骨破坏1例.②缺乏经验及综合分析欠妥者24例(53.3%).③CT表现不典型者19例(42.2%).结论 对CT征象认识不准确及过分强调某些征象是误诊的主要原因.合理而仔细的检查,并结合临床表现全面分析,加上诊断经验的不断积累,将有利于降低肺癌的CT误诊率. Objective To analyze the causes of computed tomographic misdiagnosis of pulmonary carcinoma. Methods From September 1991 to January 2002, 45 cases of pulmonary carcinoma misdiagnosed by CT were analyzed retrospectively. Twenty-six cases of pulmonary tuberculosis and 15 cases of pulmonary pneumonia misdiagnosed as pulmonary carcinoma by CT were studied as control subjects. All of these cases were confirmed by surgery and clinical course. The CT appearances of these cases were independently reviewed in a double blind method by three experienced radiologists. Then they discussed together in order to search for the factors of CT misdiagnosis and formed a consensus interpretation. Results
