Cases of Multiple Tracheobronchial Diverticulosis Characterized by Recurrent Pneumonia Episodes

Tracheal diverticulosis is a rare tracheal pathology that occurs in approximately 1-2% of the population. In order to draw attention to this rare tracheal pathology, we would like to present two cases in which tracheal diverticula were accompanied by bronchial diverticula. Case 1: A 58-year-old male patient presented to our outpatient clinic with a weight loss of approximately 7 kg in 1 month. Computed tomography (CT) revealed multiple tracheal diverticula in the trachea and bilateral main bronchi. Case 2: A 52-year-old male patient was admitted with complaints of right-sided pain and fever. CT and fiberoptic bronchoscopy revealed multiple diverticula in the bilateral bronchial system. Tracheal diverticula are paratracheal air cysts protruding from the tracheal wall. They are usually detected incidentally on imaging because patients are usually asymptomatic. Approximately 97% of the lesions are located in the right posterolateral wall and are usually solitary. The association between multiple and bronchial diverticula is very remarkable.
