Presence of tracheal bronchus in children undergoing flexible bronchoscopy

Tracheal bronchus is a rare morphological anomaly of the tracheobronchial tree. Most often TB is associated with other birth defects such as another tracheo-bronchial tree malformation, vascular abnormality, congenital heart malformation or in the context of a syndromic pattern. A relationship between respiratory symptoms and the presence of TB is very rare and selective treatment is infrequent.
