Excerpted from the GeneReview: Congenital Diaphragmatic Hernia Overview
Congenital diaphragmatic hernia (CDH) is characterized by: (1) incomplete formation/muscularization of the diaphragm resulting in absence or deficiency of the diaphragm, or (2) eventration resulting in elevation of a portion of the diaphragm that is thinned as a result of incomplete muscularization. Diaphragmatic hernias include posterolateral (Bochdalek) hernias, Morgagni and other anterior hernias, and (rarely) central hernias. About 50%-60% of affected individuals have isolated CDH; the remainder have complex CDH – that is, CDH occurring with additional malformations or as part of a single-gene disorder or chromosome abnormality. Infants with CDH often present in the neonatal period with severe respiratory distress; pulmonary hypoplasia is common. Presenting symptoms after infancy can be acute onset of respiratory or gastrointestinal distress or abdominal pain from chronic intestinal obstruction or pleural effusion from entrapment of the bowel in the chest.
