Tracheal diverticula in infants: a report of three cases.

Tracheal diverticulum is a paratracheal air cyst in connection with the trachea. It may be congenital or acquired. Congenital tracheal diverticula in infants are rare. Imaging techniques such as high-resolution computed tomography and three-dimensional reconstruction of the airway are useful for diagnosis. Here we report three cases with congenital tracheal diverticula, which were diagnosed by imaging techniques.
