Congenital diaphragmatic eventration associated with massive hiatal hernia.

Congenital eventration of the diaphragm is uncommon. Its association with a hiatal hernia has not been reported earlier. We report a case of such an association in a 2-month-old boy who presented with tachypnea aggravated by feeding and recurrent vomiting. Diagnostic uncertainty and a unique course of postoperative recovery complicated by gastric volvulus are described. The patient underwent surgical plication of the right diaphragm, followed by an emergency hiatal repair on the first postoperative day. Timely recognition, and repair of the hiatal hernia averted a fatal complication.
