Lateral posterior choroidal artery

The lateral posterior choroidal artery may be a singular structure or exist as multiple lateral posterior choroidal arteries. In both cases, they arise from the P2 segment of the PCA, just distal (and lateral) to the medial posterior choroidal arteries. In some cases, they may arise from one of the PCA branches (parieto-occipital).

They pass from the ambient cistern (cisternal segment) into the choroidal fissure and supply the choroid plexus (plexal segment) of the lateral ventricle. Anteriorly they anastomose with the distal branches of the medial posterior choroidal artery, which ascend through the foramen of Monro.
