Morgagni”s Hernia

Key Points:

A hernia usually occurs on the right side but may occur on the left or in the midline. It has also been described as retrosternal, parasternal and substernal in location. It occurs in a potential space, which is produced by the failure of the septum transversus of the diaphragm to fuse with the costal arches. This anatomic defect gradually increases and causes herniation through the foramen sometime later in life.

It is a direct hernia, which always contains a peritoneal sac. It is the least common of the diaphragmatic hernias and comprises only 3% of all repaired hernias. Although considered to be a direct congenital hernia it is rarely diagnosed during the first years of life, and unlike other types of diaphragmatic hernias is rarely associated with other congenital anomalies. The most common contents of a hernia are Omentum and Transverse Colon. Can also contain Stomach, Liver, Cecum, terminal ileum, and ascending colon.
