Abstract

The posterior communicating artery (PCoA) arises from the cerebral part of the internal carotid artery and reaching the interpeduncular cistern unites with the posterior cerebral artery, marking the beginning of its post-communicating part. We accidentally found a case of an unusual origin and termination of the right PCoA associated with a presence of the right olfactory artery remnant in a 35-year-old male cadaver routinely dis-sected at Institute of Forensic Medicine. Presented vascular variations have not been reported previously in the literature. In the event of PCoA origin from the right middle cerebral artery normally developed from the cra-nial end of primitive internal carotid artery, as well as the PCoA junction with basilar tip, this PCoA could be the most cranial carotid-basilar anastomosis. Simultaneously, here presented right olfactory artery remnant could be the third variant of this persistent embryonic artery.
