RESUMEN
Objective To evaluate CT and bronchofiberscopic value in diagnosing bronchogenic stenosis.Methods The CT and bronchofiberscopic appearances of bronchogenic stenosis in 45 cases were analysed comparatively with the results of the pathological examinations.Results Among the 45 cases, there were central pulmonary carcinoma in 25 patients, endobronchial tuberculosis in 10 patients, bronchogenic pneumonia in 9 patients and radiation pneumonia in 1 patient all confirmed pathologically. Conclusion CT and bronchofiberscope are of respectively advantages in diagnosing bronchogenic stenosis,combining both of them,the diagnosis and differential diagnosis of bronchogenic stenosis can be improved.
