Intrapericardial diaphragmatic hernia: report of 2 cases with prenatal diagnosis.

An intrapericardial diaphragmatic hernia is a very rare congenital abnormality, with only a few cases reported in the English literature. The triad includes a massive pericardial effusion, bilateral pulmonary compression with or without pulmonary hypoplasia, and herniation of part of the liver into the pericardium. We report 2 cases of intrapericardial diaphragmatic hernias diagnosed prenatally in our obstetrics and gynecology unit.
