Fistula formation between the right and left main bronchus caused by endobronchial tuberculosis.
The prevalence of endobronchial tuberculosis (EBTB) in patients with active tuberculosis is about 10% to 40%. The most common complication of EBTB is bronchial stenosis. Fistula formation by pulmonary tuberculosis is a very rare complication and is most commonly bronchopleural. The authors present a 53-year-old woman presented with chronic cough and abnormality in chest computed tomography scan. According to chest computed tomography scan finding, bronchoscopic study was done and bronchial lavage was obtained. Bronchial lavage was positive for acid fast bacilli. Bronchoscopy showed fistula formation between the right and left main bronchus, a rare manifestation of EBTB. The patient was treated with antituberculosis therapy, and her symptoms improved and radiological findings showed regression of pulmonary lesions.
