32例肺癌X线误、漏诊病例分析

ANALYSIS OF X-RAY MISDIAGNOSIS ANDMISSED-DIAGNOSIS OF LUNG CANCER IN 32 CASES

笔者报告了３２例Ｘ线误、漏诊肺癌病例，其中误诊为肺炎及肺结核２０例，占全部误、漏诊病例的６２．５％，误诊为其它疾病占２４．９％。可见肺癌的误诊主要在常见疾病之间。漏诊４例，占全部误、漏诊病例的１２．５％，肺癌的漏诊多因与周围正常结构重叠所致。回顾分析，由于经验不足，检查方法不全而误、漏诊占３７．５％，由于缺乏定性诊断的Ｘ线表现，诊断比较困难者占５９．４％。作者认为积累Ｘ线诊断经验，进行全面系统的Ｘ线检查，对Ｘ线诊断困难者进一步进行ＣＴ检查可减少肺癌的误、漏诊率。

cases of x-ray misdiagnosis and missed -diagnsosis of lungcancer were reported. 20 cases (62. 6% )were misdiagnosed as pneumonitisand TB,8 cases (12. 5% )were missed-diagnosis.
