Abstract: Objective To describe CT signs of endobronchial tuberculosis (EBTB) and to make a further understanding of the disease.Materials and Methods Thoracic CT findings in 18 cases with pathologically-proved EBTB were retrospectively analyzed. The abnormalities of the bronchi, pulmonary parenchyma, lymph nodes and pleurae were observed.Results A total of 21 bronchi was affected. The right lung was more affected than the left lung, with the lower lobes being most frequently involved. Bronchial wall thickening was seen in 16 sites, bronchial stricture and occlusion in 13 and 5 sites, respectively. The diseased segment of the bronchus was over 3cm in 10 sites. Thickened wall with localized dilatation of the bronchus was present in 5 sites. Secondary atelectasis (n=5) and bronchial dissemination (n=11) were observed. Old pulmonary tuberculosis was present in all patients, and fresh tuberculous lesions in 8 patients. Pleural lesion was noted in 15 cases. Mediastinal or hilar tuberculous lymphadenitis was demonstrated in 9 cases. Conclusion Concentric bronchial wall thickening which affects a certain segment of the bronchus is the main sign of EBTB. Pulmonary and pleural lesions are coexisted in most cases. Circle enhancement of the lymph nodes is characteristic.
