[Congenital diaphragmatic hernia: a condition which is not always easy to diagnose]

Congenital hernia of the diaphragmatic dome (CDC) is a congenital embryopathy where all or part of the diaphragmatic dome fails to form. Its rate is 1/3500 live births with a male predominance. This study reports a case of Bochdalek hernia as well as data in the literature and highlights the diagnostic and therapeutic challenges in this disease. Diagnosis and antenatal management are essential to reduce patient's mortality and morbidity. Prognosis is poor and depends on the presence and degree of pulmonary hypoplasia and on the association with congenital malformations.
