Incidental Congenital Diaphragmatic Hernia (Bochdalek) in an Asymptomatic Adult: A Case Report and Review of Literature

Congenital Diaphragmatic Hernias (CDH) is a rare entity with incidence of 1:3000 live births. Late presentation is unusual and in most cases is diagnosed in adolescents or early childhood. Asymptomatic diaphragmatic hernia in the absence of trauma is very rare in adults. The finding of CDH in adults is mostly incidental. Left sided hernia i.e. Bochdalek hernia is more common. It is more commonly associated with other anomalies. The morbidity and mortality are mainly due to pulmonary hypoplasia. We report a case of CDH, posterolateral defect (Bochdalek type), with left lung hypoplasia in a middle aged man, who was asymptomatic throughout the life and presented to us incidentally when he was referred following anOrthopaedic trauma.We discuss the index case and other causes of diaphragmatic hernia.
