One case of tracheal diverticulum and eleven cases of bronchial diverticula were detected in 4127 subjects examined by fiberscopic bronchoscopy. The tracheal diverticulum was located in the right posterior portion of the trachea, and the bronchial diverticula were located in the right truncus intermedius (5 cases), the right basal bronchus (5 cases) and the right middle lobe bronchus (1 case). From our studies and reviewing the previous reports in Japan, we came to the conclusion that the frequent site of the tracheal diverticulum was at the right posterolateral portion and that of the bronchus was at the truncus intermedius. There was redness of the mucosa and vascular engorgement in 2 of the 12 cases of tracheobronchial diverticula. In most cases, diverticula were clinically silent, however in some cases, they tended to lead to the foci of inflammation. Therefore in case of the recurrent pulmonary inflammation, bronchofiberscopic examinations are highly recommended to rule out the tracheal or bronchial diverticula.
