title: Persistent external carotid-vertebrobasilar anastomosis via the hypoglossal canal.
abstract: A persistent external carotid-vertebrobasilar anastomosis, associated with intracranial aneurysms, was identified. The anomalous vessel passed through the hypoglossal canal, and was possibly a variant of the persistent primitive hypoglossal artery.
