Incidental discovery of multiple tracheal diverticula.

Tracheal diverticulum is observed in 1%-4% of the population, however, multiple tracheal diverticula are a rare occurrence. In this paper, we present a 75-year-old male, who was referred to a computed tomography-scan of the neck, chest, abdomen, and pelvis because of an unintended weight loss, fatigue, and a smoking history of 60 pack-years. A definitive cause for the symptoms was not found, however as an incidental finding, the patient was diagnosed with multiple tracheal diverticula along the back wall of trachea and left main bronchus. Despite the rare occurrence, it is important to recognize multiple tracheal diverticula in the diagnostic process, because of the possibility of either removing the diverticula or initiating prophylactic actions to prevent complications such as empyema and pneumomediastinum.
