Detailed explanation-1: -The posterior inferior cerebellar artery (PICA) is the largest branch of the vertebral artery. It is one of the three main arteries that supply blood to the cerebellum, a part of the brain. Blockage of the posterior inferior cerebellar artery can result in a type of stroke called lateral medullary syndrome.
Detailed explanation-2: -The PICA supplies the medulla, the choroid plexus and tela choroidea of the fourth ventricle, the tonsils, the inferior vermis, and the inferior aspects of the cerebellar hemispheres 1, 7.
Detailed explanation-3: -Wallenberg syndrome (WS) is a neurological disorder that is due to damage to the lateral portion of the medulla oblongata (i.e., the lateral medullary syndrome). WS is typically due to ischemia from a vertebral artery or posterior inferior cerebellar artery infarction.
