Diaphragmatic Eventration

Michael P. D'Alessandro, M.D.
Peer Review Status: Internally Peer Reviewed

Clinical Presentation:
Usually are asymptomatic or have mild respiratory distress.

Abnormal elevation of the diaphragm due to absent or deficient diaphragm muscles with only the peripheral thoracic attachments showing normal muscle. There are two types: (1) congenital, due to defective diaphragm muscle formation and (2) acquired, due to atrophy of diaphragm muscles secondary to prenatal or postnatal phrenic nerve injury. The acquired type is the most common.

Marked decrease in muscle fibers between the parietal pleura and the peritoneum. The affected area appears membranous.

Imaging Findings:
Generalized elevation of the diaphragm with the abdominal viscera contained by a thin but intact diaphragm.
