title: Fistula Formation between Right Upper Bronchus and Bronchus Intermedius Caused by Endobronchial Tuberculosis: A Case Report.
abstract: Endobronchial tuberculosis is defined as a tuberculous infection of the tracheobronchial tree and has a prevalence of up to 50% in active pulmonary tuberculosis cases. The most common complication of endobronchial tuberculosis is bronchial stenosis; benign fistula formation by endobronchial tuberculosis is rare, especially inter-bronchial fistula formation. We reported a rare case of a 73-year-old woman with a fistula between the right upper bronchus and bronchus intermedius. A diagnosis of inter-bronchial fistula caused by endobronchial tuberculosis was based on the results of chest computed tomography scans, bronchoscopy, and microbiological and pathological tests. The patient was treated with anti-tuberculous medication, and her symptoms gradually improved.
