The basilar artery terminates at the pons/midbrain junction by bifurcating into the posterior cerebral arteries (PCA). Multiple penetrating branches of the pons originate directly from the basilar artery. AICA supplies the ventrolateral inferior pons and anterior inferior cerebellum, whereas the SCA supplies the lateral rostral pons and caudal midbrain and the entire superior surface of the cerebellum. The basilar artery gives rise to paired anterior inferior cerebellar arteries (AICA) and superior cerebellar arteries (SCA). Occlusion of this vessel gives rise to Wallenberg’s or PICA Syndrome. Anatomically the infarcted area in Wallenberg syndrome is supplied by the posterior. The syndrome can also be due to occlusion of the vertebral artery, or the inferior, middle, or superior medullary vessels. , which results from occlusion of either the. The primary pathology of Wallenberg syndrome is occlusion of the posterior inferior cerebellar artery (PICA) or one of its branches (2).

The vertebral artery gives rise to the posterior inferior cerebellar artery (PICA) the latter vessel supplies the dorsolateral medulla and the posterior and inferior surfaces of the cerebellum. Wallenberg syndrome is a neurological condition caused by a lateral medullary. They then unite at the caudal border of the pons to form the midline basilar artery. The vertebral arteries enter the cranium via the foramen magnum and course superiorly along the ventrolateral surface of medulla. Blood supply of the brainstem. The blood supply of the brainstem and cerebellum is derived entirely from branches of the vertebrobasilar circulation.
