From: An excess vessel in the posterior part of the human cerebral arterial circle (CAC): a case series
Modified (a) and original (b-c) pictures of some cerebral arteries on the basal surface of the brain: right ICoA (arrow) is presented in the posterior part of the CAC. Insert - a. Right posterior cerebral artery, pre-communicating part of carotid origin (PCA-P1c); right posterior cerebral artery, pre-communicating part of basilar origin (PCA-P1b); right posterior cerebral artery, post-communicating part (P2); left posterior communicating artery (PCoA). Some vascular components are labeled by numerals: 1-2, left and right internal carotid arteries, choroidal and communicating subparts of cerebral part; 4, right anterior cerebral artery, pre-communicating part; 6, basilar artery. Insert - c. *, right anterior choroidal artery.
