Persistent hypoglossal artery

Case contributed by Dr Amir Rezaee

Left persistent hypoglossal artery arising from proximal internal carotid artery. Note enlarged left hypoglossal canal.

Case Discussion

A persistent hypoglossal artery is one of the persistent carotid-vertebrobasilar anastomoses. After passing through an enlarged hypoglossal canal, it joins the basilar artery inferiorly. If large, the ipsilateral vertebral artery and PCOM are often hypoplastic or absent. There is an association with concurrent aneurysms.
