Anastomosed triplicated branches of the superior cerebellar arteries: a rare case of cerebral arterial plexus

Abstract

Triplications of the superior cerebellar arteries are rare cases but when present are culminating factors to thromboembolism and arterisclerosis leading to infarction of areas supplied. We present a rare case of arterial plexus, where there were not only triplicated branches of the superior cerebellar but these anastomosed forming a single branch that later bifurcated normally lateral to the cerebral peduncles. This kind of formation is attributed to embryological malfusions of primitive neural arteries towards the basilar trunk. Anastomosis can be clinically important in neurovascular surgery ligation therefore caution should be taken not to damage the forming branches.
