Aberrant Direct Origin of the Cerebellar Arteries From the Internal Carotid Artery

The persistence of carotid-basilar anastomoses is a well known but rare condition, with the trigeminal artery being the most common. Cerebellar arteries originating directly from the internal carotid artery are considered variants of the persistent trigeminal artery and are less known. The authors present 3 cases of anomalous origin of the cerebellar arteries from the internal carotid artery and a review of the literature to elucidate their etiology and clinical implications. Although these anatomic variants are often an incidental finding, their recognition is important to explain atypical clinical presentations and for preoperative planning of surgical and endovascular procedures.
