The posterior choroidal arteries, while often referred to as a single posterior choroidal artery, actually comprise of up to 11 arteries per hemisphere.

They are divided into medial posterior choroidal artery and lateral posterior choroidal artery groups. They usually arise from the P2 segment of the posterior cerebral artery and supply components of the brainstem and the pineal gland.
