The anterior choroidal artery is a branch of the internal carotid artery.
Anatomy
As a rare variant, the anterior choroidal artery may also arise from the middle cerebral artery.
Territory of supply
The anterior choroidal artery supplies, in particular, the choroid plexus, the posterior part of the internal capsule, and parts of the visual pathway.
Clinical manifestations of occlusion
The classic clinical symptoms of anterior choroidal artery occlusion are contralateral hemiparesis, hemihypesthesia, and homonymous hemianopsia1. If the occlusion is localized on the dominant side, mild aphasia may also occur.
