Tracheal diverticulum: a review of the literature.

Author information

Pneumology Service, Carlos Haya Hospital, Malaga, Spain.


Tracheal diverticulum is a rarely encountered entity. It may be congenital or acquired, the difference residing mainly in the histologic features of the wall. Most cases are asymptomatic, but when symptoms are present they are usually nonspecific. Congenital diverticulum is not normally detected in infancy unless it is suggested by recurrent episodes of tracheobronchial infection or in associated with other malformations. Imaging techniques are useful for diagnosis because the point of communication with the trachea is difficult to detect with bronchoscopy. In the absence of symptoms, management should be conservative. We review the entity and report two new cases, one a casual finding in a 49-year-old man and the other in a 63-year-old woman who presented with occasional bloody sputum.
