Left tracheal bronchus in an infant with laryngeal cleft

Laryngeal cleft, a rare congenital anomaly, may occur in association with other airway abnormalities. Despite the close proximity of embryologic development of the laryngotracheobronchial tree, bronchial abnormalities in association with laryngeal cleft have not been widely reported. We describe the left tracheal bronchus, an uncommon anomaly of the tracheobronchial tract, in an infant with laryngeal cleft. Coexistence of rare tracheobronchial anomalies needs to be considered in the presence of laryngeal cleft. Early recognition of tracheal bronchus may prevent complications of endotracheal intubation and improve the management of potential complications such as recurrent pneumonia, atelectasis, and hemoptysis.
