Diaphragmatic lung hernia

Last revised by Daniel J Bell on 17 Apr 2022

A diaphragmatic lung hernia (plural: hernias or herniae) is extremely rare, characterized by a lung herniation through the diaphragm into the abdominal cavity. There has been a single case report 2. It is questionable whether this entity truly exists at all 3.

This is not to be confused with the far more common congenital or traumatic diaphragmatic hernias, in which abdominal contents pass through the defect into the thorax.
