PICA ischemic stroke

The posterior inferior cerebellar artery (PICA) has a unique anatomical complexity, which is of great clinical importance and involved in many pathologies, such as aneurysm, ischemic stroke, neurovascular compression syndrome (NVCS), arteriovenous malformation (AVM) brain tumour (1).
 PICA sinuous variable trajectory, divided into 5 segments. infarction usually manifests lateral bulbar more likely to cause mass effects. frequently compresses the bulb cranial nerves, resulting various syndromes (NVCS) (2).
 stroke caused by thromboembolism segment accounted for than 2% all cases (3). Moreover, it tends be underdiagnosed due symptomatology, represented vertigo mimics possible peripheral vestibulopathy (4).
