Callosomarginal artery

The callosomarginal artery (also known as median artery of corpus callosum) is the largest branch of the pericallosal artery. It runs in or posteriorly to the cingulate sulcus and runs a course parallel to the pericallosal artery where it divide to give two or more cortical branches to supply the frontal lobe, paracentral area and anterior parietal lobe.

Variant anatomy

The callosomarginal artery can be quite variable in its origin, arising from anywhere along the A1 to A4 segments of the anterior cerebral artery (ACA).
