Foreign body aspiration in a rare tracheal anomaly: A case report

INTRODUCTION: Tracheal bronchus is a rare anomaly in which an accessory bronchial branch originates superior to the tracheal bifurcation. It is usually incidentally found in patients with recurrent chest infection, persistent stridor and less commonly due to foreign body aspiration. PRESENTATION OF CASE: A 6-year-old medically and surgically free boy presented to the Emergency Department with severe shortness of breath. The patient was initially saturating well, but then suddenly worsened and was rushed for intubation. The patient was taken to the operating room for direct laryngobronchoscopy to retrieve the foreign body obstructing the airway. The foreign body was successfully retrieved, and the presence of a tracheal bronchus was confirmed. DISCUSSION: The presence of tracheal bronchus has its implications on airway management. CONCLUSION: Knowledge about tracheal bronchus is of great importance to the otolaryngologist and anesthetist to maintain the airway.
