A Rare Case of Tracheobronchial Anomalies: ‘Tracheal Bronchus’

Tracheal bronchus is a rarely seen congenital anomaly of the bronchial tree. This anomaly may cause a variable spectrum of clinical findings, ranging from asymptomatic patients to recurrent pulmonary infections. Recently, the number of cases diagnosed has increased due to the widespread use of flexible bronchoscopy and multislice tomography. A case of tracheal bronchus accompanying trisomy 21 is presented along with information from the literature.
