Trigonum sternocostale

Trigonum sternocostale (Larrey's fissure/fissura) is a fissure between the pars costalis diaphragmatis and pars sternalis diaphragmatis. The vasa epigastrica superiora runs ventrally.

Penetration of diaphragmatic hernias may occur in this area. In such a case, it is a so-called Morgagni hernia.
