Case of congenital bronchial atresia detected by fetal ultrasound.

Congenital bronchial atresia is an anomaly characterized by a mucocele associated with a blindly terminating segmental or lobar bronchus. We report on a case of congenital atresia of the left superior segmental bronchus (B6) followed by fetal ultrasonography, which showed a large simple cyst with a surrounding small echogenic area. A large cyst and persistent lung fluid in the affected segment were noted in the early neonatal period. Copyright 2003 Wiley-Liss, Inc.
