Congenital diaphragmatic hernia in the adult.

The onset of symptoms from a congenital posterolateral (Bochdalek Hernia) defect is rare in the adult. We are reporting a 25-year-old female with a previously asymptomatic Bochdalek hernia who presented with acute intestinal obstruction. The abnormal embryology, pathophysiology, and clinical manifestations of this condition in the adult are discussed.
