Morgagni's hernia is an uncommon type of diaphragmatic hernia in the pediatric age group. Out of 52 children with different types of congenital diaphragmatic hernia that we have treated, 5 (9.6%) had Morgagni's hernia. There were 2 infants and 3 children including one with Down's syndrome. All suffered from repeated attacks of chest infection, and only after a chest X-ray was the diagnosis of Morgagni's hernia suspected. In 2 cases this appeared as an opacity in the anterior mediastinum adjacent to the pericardium; diagnosis was confirmed by barium enema in one and a CT-scan in the other. The remaining 3 cases showed anterior herniation of bowel loops on chest X-ray which was bilateral in one. This bilaterality was confirmed pre-operatively by CT scan. Associated anomalies were present in all cases, including 2 with malrotation. All patients were treated surgically via a transabdominal approach. Our study shows a relative high frequency of Morgagni's hernia in our patients and, although late-presenting Morgagni hernias are relatively benign, it can cause significant morbidity. This calls for early diagnosis and early referral for surgery. Chest X-ray is to be strongly advocated in children with repeated attacks of chest infection.
