case_images: The origin of this artery is on C4 segment superolateral surface, it has a sinous aspect, it form al loop with lateral convexity at 18o, descends in cavernous sinus, medial to trigeminal nerve ophthalmic branch, comes in direct contact with abducens nerve at it entrance into cavernous sinus (Fig. 13), is positioned inferior to oculomotor nerve, angulates at 700 turn posteriorly and medially, it traverse Meckel cavum medial and inferior to trigeminal ganglia, pierces dura and change direction at 90o, becoming horizontal in prepontine cistern where it's anastomosing with basilar artery inferior to superior cerebellar artery origin (Fig. 14).
