Persistent trigeminal artery variant terminating in the posterior inferior cerebellar artery: a case report

Ga Young Lee et al. Surg Radiol Anat. 2018 Feb.

Abstract

Persistent trigeminal artery (PTA) is a rare cerebrovascular variation of remnant fetal carotid-vertebrobasilar anastomoses. The PTA variant terminates in the cerebellar artery with no direct connection to the basilar artery. We present a rare case of a PTA variant that terminated directly into the ipsilateral posterior inferior cerebellar artery.

Keywords: Internal carotid artery; Persistent trigeminal artery; Posterior communicating artery; Posterior inferior cerebellar artery.
