Abstract

A tracheal bronchus, an aberrant bronchus arising directly from the trachea, is an infrequent congenital anomaly. The incidence of this anomaly ranges from 0.5 to 5%. It usually originates from the right lateral wall of the trachea at the level <2 cm above the tracheal bifurcation. These patients usually are asymptomatic, but some patients may experience recurrent pneumonia, chronic bronchitis, bronchiectasis, or asthmatic episodes. A tracheal bronchus may be associated with other anomalies such as a tracheal stenosis, pulmonary agenesis, pulmonary sequestration, congenital heart disease, a pulmonary venous anomaly and Down's syndrome. This anomaly is usually diagnosed incidentally during bronchoscopy in patients with respiratory problems. Here we report a case of a 20-year-old man with a past history of bronchial asthma, which was incidentally diagnosed as a tracheal bronchus during a medical examination prior to military service, and was associated with a bilateral superior vena cava anomaly.
