支气管内膜结核的CT特征探讨及漏误诊分析

Analysis of CT characteristics and misdiagnosis or missed diagnosis of endobronchial Tuberculosis

目的:探讨支气管内膜结核(Endobronchial tuberculosis,EBTB)的CT诊断,分析漏、误诊原因。方法:回顾性分析28例经确诊的EBTB的胸部CT表现。结果:EBTB主要表现为支气管内壁不规则增厚,管腔不规则狭窄,受累范围较长,常与肺内结核并存。CT易误诊为支气管肺癌、慢性支气管炎、支气管扩张、慢性肺炎等疾病;临床认识不够、观察分析不全面、忽视CT薄层扫描价值等是本病漏诊的重要原因。结论:EBTB的CT表现具有一定特点,加强临床认识、综合分析、重视CT薄层扫描可有效防止漏误诊。

Objective：To discuss the CT characteristics of endobronchial tuberculosis and reasons for misdiagnosis or missed diagnosis of the disease.Methods：Retrospective analysis was used for CT characteristics of 28 cases with definite endobronchial tuberculosis.Results：CT characteristics of endobronchial was irregular thickness of bronchus inner wall lumens irregular stenosis being long involved in scope and often concomitant with lung tuberculosis,which could easily lead to misdiagnosis as bronchiogenic carcinoma,chronic bronchitis,bronchiectasis,chronic pneumonia,etc.Clinical know enough,observation analysis is not comprehensive,ignoring the CT TLC scanning value this disease is the important reason capsulorrhaphy.Conclusion：Endobronchial tuberculosis has particular CT characteristics.With improved clinical recognition,comprehensive analysis,and the application of CT thin-slice scan,misdiagnosis or missed diagnosis can be prevented.
