Tuberculous involvement of the tracheobronchial tree usually coexists with active pulmonary parenchymal orintrathoracic lymph node infection and very rarely has been showed normal chest roentgenogram. This paperdescribed 30 cases of endobronchial tuberculosis, confirmed by bronchoscopy and biopsy in correlation tobronchographic finding on the patients from Jan. 1983 to Nov. 1986 in Department of Radiology, National Medical Center. The results were as follows: 1. Sex distribution of endobronchial tuberculosis showed 8 cases(26.7%) inmale, 22 cases(73.3%) in female and the highest incidence in the third decade. 2. The radiologic findings ofinitial plain chest showed lobar or segmental collapase 16 cases(53.3%), minimal pulmonary tuberculosis 7cases(23.3%), moderately advanced pulmonary tuberculosis 4 cases(13.3%), far advanced pulmonary tuberculosis 2cases(6.7%), and normal finding 1 case(3.3%) 3. 25 cases of 28 bronchogram showed bronchial obstruction. The leftside was affected slightly more than the right(14:11). 4. The obstruction site of bronchus showed complete obstruction in 11 cases, among them sharp cut off in 2, rat tail narrowing in 1, symmetrical V-shaped narrowing in8, and incomplete obstruction in 14 cases, among them thumb printing indentation in 2, circumferential symmetrical narrowng in 12. 5. 10 cases of 25 obstruction showed an associated bronchiectatic change of distal or adjacent tothe lesion site, among them tubular in 3, saccular in 2, cystic in 5 cases.
