Abstract
Delayed herniation of the abdominal contents through a congenital diaphragmatic hernia may occur beyond the neonatal period. This report describes a 9-week-old female baby who presented with excessive crying, irritability and respiratory distress secondary to late presentation of left-sided congenital diaphragmatic hernia. The chest radiograph showed tension gastrothorax. She underwent surgical reduction of the hernia. She made an excellent recovery and was discharged a few days after the operation. It is assumed that sudden increase of the intra-abdominal pressure caused herniation of abdominal content through a pre-existing diaphragmatic defect. This report aims to increase the awareness of this condition among physicians and pediatric surgeons to allow early diagnosis and management.
