The anterior choroidal artery, which may be a single vessel or a plexus of small vessels, arises from the posterior medial C7 segment superior to the posterior communicating artery. There are two branches of the anterior choroidal artery, cisternal and intraventricular. The cisternal branch courses posteromedially within the crural cistern around the cerebral peduncle towards the lateral geniculate body of the thalamus, turning sharply medially to enter the temporal horn through the choroidal ﬁssure.
This artery is signiﬁcant for two reasons: ﬁrst, it supplies cranial nerves III, IV, and VI, the Gasserion ganglion, and the cavernous sinus dura; second it forms external carotid artery (ECA) to ICA (ECA–ICA) collaterals via the artery of foramen rotundum with the internal maxillary artery and via posterior branches with the middle meningeal artery and maxillary artery. The least consistent of the C4 segment branches is the capsular artery of McConnell, which is seen in 28% of individuals and supplies the pituitary gland.
