Atypical distal tracheal fibrous bridge and bronchial stenosis in an adult patient with bronchopulmonary dysplasia.

Tracheobronchial stenosis (TBS) in adults derives from congenital and acquired conditions, including prolonged mechanical intubation, expiratory central airway collapse, infectious or inflammatory disease, and malignancy. The most common clinical presentation is shortness of breath, recurrent infections, and chronic cough. TBS is usually diagnosed via computed tomography or bronchoscopy, with the latter doubling as a therapeutic tool. We present a case of an atypical fibrotic bridge connecting the walls of the distal trachea and fibrotic bronchial stenosis treated with electrocautery knife and balloon dilation, in an adult patient with bronchopulmonary dysplasia.
