“…Infundibula are commonly encountered anatomical variants present in the cerebral arterial circulation and represent limited pathological consequences [ 1 ]. Infundibula arising from the ICA origin of the PCoA are common; however, those arising from the PCA origin are exceedingly rare, and at the time of writing we are unaware of any previous report of this variant [ 5 ].…”

Infundibula are funnel-shaped lesions that develop at the intersections of major intracranial arteries. These lesions are prone to being misdiagnosed as intracranial aneurysms. The most common arterial infundibula have been noted in the posterior communicating artery (PCoA) branch of the internal carotid artery (ICA). Digitally subtracted angiography performed included catheter angiography of the vertebral artery and ipsilateral carotid to evaluate the suspected lesion. Right vertebral angiography demonstrated an infundibulum seen at the right PCoA/posterior cerebral artery (PCA) junction, with noted posterior-to-anterior circulation dominance of the Circle of Willis collateral flow. We report a case of posterior communicating artery infundibulum arising from the posterior cerebral artery origin in a 38-year-old man.

“…The posterior communicating artery (PCoA) branch of the internal carotid artery (ICA) is the most common site of cerebral infundibula [ 1 ]. Infundibula are similar in appearance to aneurysms, leading to frequent misdiagnoses.…”
