Thoracoscopic Resection of a Rare Congenital Lung Lesion With a Tracheal Bronchus.

A tracheal bronchus is a rare anatomic variant characterized by a bronchus originating from the trachea rather than the carina. These are most commonly asymptomatic and found incidentally but can cause recurrent pneumonias in children. Here, we present a case of a thoracoscopic resection of an azygous lobe with a tracheal bronchus in a 9-year-old female.
