The pericallosal artery is a branch of the anterior cerebral artery.
Anatomy
Course
The pericallosal artery courses in the Cisterna laminae terminalis and then between the two hemispheres in the interhemispheric fissure above the Corpus callosum. It curves around the genu of the corpus callosum and then courses posteriorly along the corpus callosum[^1].
Size
The average diameter of the pericallosal artery at its origin is approximately 2.9 mm on the right and approximately 2.5 mm on the left[^1].
Supply
The branches of the pericallosal artery provide the primary blood supply to the Corpus callosum, the Cingulate gyrus, and the medial surface of the Parietal lobe[^1].
