The sternocostal triangle (foramina of Morgagni, Larrey's space, sternocostal hiatus, etc.[1]) are small zones lying between the costal and sternal attachments of the thoracic diaphragm. No vascular elements are present within this space.[2] The borders of this space are:
Medial: the lateral border of the sternal part of the diaphragm
Lateral: the medial border of the costal part of the diaphragm
Anterior: the musculoaponeurotic plane formed by a confluence of the transversus thoracis superiorly and the transversus abdominis inferiorly
The superficial epigastric artery passes in front of the aponeurotic plane that forms the anterior border and enters the abdomen anterior to the diaphragm.[2]
Eponym
[edit | edit source]It is named for Giovanni Battista Morgagni.[3]
Pathology
[edit | edit source]It can be a site of Morgagni's hernia.
