Tracheobronchial tuberculosis is the tuberculous affection of tracheobronchial wall mainly due to direct implantation of infected sputum through airway. When inflammation extends deeply into the bronchial mucosa, causing ulceration and necrosis, healing can occur with fibrosis and result in bronchial stenosis. There have been many reports of simple chest findings and bronchographic findings about trachebronchial tuberculosis. But there is no report about CT findings of tracheobronchial tuberculosis. We reviewed and analysed CT findings of 15 cases of tracheobronchial tuberculosis which were examined during the period form January 1987 to August 1989. The diagnosis was based on bronchoscopic biopsy (5), positive sputum, AFB (5), or previous antituberculous medication with typical bronchoscopic finding (5). All 15 patients were studied with a GE-9800 scanner after injection of intravenous contrast media injection. The results were as follows. 1. Of the 15 cases, 13 cases were fe ale and 2 cases were male. Most patients were female in their twenties or thirties. 2. The CT findings of endobronchial lesion are luminal obstuction in 6, increased wall thickness in 9, walll enhancement in 2, surrounding fat plane obliteration in their twenties or thirties. 3. CT CT and bronchoscopy, equally detected bronchial lesions in 8 cases. CT was superior in 4 cases and bronchoscopy was superior in 2 cases. 4. The most frequently affected site was left main bronchus 98), followed by trachea (4), right main bronchus (4), right bronchus intermedius (4), RUL bronchus (3), LUL bronchus (3), LLL bronchus (3), RML bronchus (1), RLL bronchus (1). 5. There were 8 cases of surrounding lymphadenopathy and 7 cases of surrounding calcified lymph node. Mainly right paratracheal and tracheobronchial lymph node enlargement were observed. 6. The findings of parenchymal lesion were ill-defined nodule in 10, ateletasis in 9, bronchiectasis in 8, emphysema in 7, consolidation in 5 and cavity i 2, No parenchmal leison observed in 1 cases. Tracheobronchial stenosis, involving concentrically and long segment, in a relatively young female patient without visible mass around the stenotic segment are the typical findings of tracheobronchial tuberculosis.
