A rare variant of persistent trigeminal artery: cavernous carotid-cerebellar artery anastomosis--a case report and a systematic review.
We report a very rare anomalous anatomic variant of the cavernous internal carotid artery supplying directly the posterior inferior cerebellar artery, with no basilar artery opacification. A systematic review as well as a description of other variants of trigeminal-cerebellar anastomosis is given.
