The most common type of diaphragmatic hernia occurs when visceral organs go through the foramen of Bochdalek (a posterolateral defect), caused by maldevelopment or defective fusion of pleuroperitoneal membranes during embryonic development [1]. An anteromedial retrosternal herniation through the foramen of Morgagni is less common. Bochdalek hernias are more common on the left, while Morgagni hernias occur mostly on the right. Stomach, bowel, and even spleen may herniate into the left hemithorax; on the right, part of the liver may go through the defect. Patients' symptoms depend on the degree of herniation. Patients with small hernias may have no symptoms, whereas patients with larger hernias may have severe respiratory distress immediately after birth [2]. Morgagni hernias usually are not large enough to cause respiratory distress at birth. Patients with Bochdalek hernias always have pulmonary hypoplasia ipsilateral and contralateral to the hernias and malrotation and abnormal fixation of the bowel [3].
        The radiologic appearance of the chest and abdomen is multiple gas-filled segments of bowel which produce a cystic bubbly appearance in the hemithorax. The mediastinum is displaced to the other hemithorax. The abdomen is usually scaphoid, lacking most of the bowel gas [4]. If herniation occurs on the right the bowel and liver or liver alone may fill the right hemithorax.
