A large vertebral artery fenestration involving the distal segments associated with bilateral duplication of the superior cerebellar artery: a case report.

This case report describes an unusual case of VA fenestration involving both extracranial and intracranial segments, along with bilateral duplication of the SCAs. While rare, these findings highlight the importance of recognizing such vascular anomalies, which could be relevant for planning surgical or endovascular procedures in the posterior circulation.
