The callosomarginal artery, also known as median artery of corpus callosum, is the largest branch of the pericallosal artery. It courses within or posterior to the cingulate sulcus, in parallel orientation to the pericallosal artery. It divides 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). In a minority of cases it may also be absent 4.
