Congenital diaphragmatic hernia
 Discussion of Congenital diaphragmatic hernia
- Congenital diaphragmatic hernia (CDH) constitutes a major surgical disease in the newborn.
- Prompt diagnosis and treatment are critical.
- Occurs in 1 of every 2000-4000 live births.
- Mortality in babies with CDH is related to pulmonary hypoplasia, persistent fetal circulation, and associated anomalies (i.e. gastric volvulus)
 Imaging Findings for Congenital diaphragmatic hernia
- Prenatal nultrasonographic features of CDH include the following: polyhydramnios; an absent or intrathoracic stomach bubble; a mediastinal and cardiac shift away from the side of the herniation.
- Classic findings: left hemithorax is filled with cystlike structures (loops of bowel), the mediastinum is shifted to the right, and the abdomen is relatively devoid of gas.
- If the chest radiograph is obtained before any air has entered the herniated bowel, diagnosing this condition with accuracy may be difficult. Similar difficulty arises when the liver alone is in the right hemithorax. In either case, the involved hemithorax is partially or totally opacified.
