[Intrauterine detection of dorsolateral diaphragmatic hernia using ultrasound].

Congenital posterolateral diaphragmatic hernia occurs in one out of 2,500 live births. Prenatal diagnosis is made via sonographic demonstration of the displaced abdominal organs that can be found in the thoracic cavity as a cystic or solid mass. Early antenatal evidence of this malformation can improve the normally poor prognosis of the newborn, as planned delivery and prompt operative treatment can be performed. Antenatal sonographic diagnosis of a left-side diaphragmatic hernia is demonstrated in two cases.
