The posterior inferior cerebellar arteriesarise from the vertebral arteries and supply the lateral medulla and inferior part of the cerebellum. However, the hypoglossal artery arising from the external carotid artery (ECA) and connecting directly with the posterior inferior cerebellar artery (PICA), instead of the basilar artery or the vertebral artery, is very rare. However, the PICA has numerous variations, and can emerge from the extracranial portion of the vertebral artery, 1) internal carotid artery, 2) primitive trigeminal artery, 3) primitive hypoglossal artery, 4) or posterior meningeal artery.
