“…PICA is the most distal and prominent branch of the vertebral artery, and it originates in the intracranial segment of the vertebral artery, in more than 40% of cases in the lateral spinal segment and almost 33% in the vertebral artery pre-medullary segment (Fig. 3) 12,[14][15][16] . In some cases, PICA occurs as the terminal branch of the vertebral artery 17 .…”

Wallenberg syndrome, or lateral medullar syndrome, is the clinical presentation of the infarct in the territory of posterior inferior cerebellar artery. Its signs and symptoms include vertigo, nystagmus, diplopia, ipsilateral Horner syndrome, facial ruddiness and dry skin, dysphonia, dysphagia, dysarthria, ipsilateral loss of gag reflex, ipsilateral ataxia, ipsilateral impaired taste, ipsilateral facial pain and paresthesia, decreased ipsilateral blink reflex, contralateral hypoalgesia and thermoanesthesia in the trunk and limbs; and ipsilateral facial hypoalgesia and thermoanesthesia. Neuroanatomical knowledge is essential to its comprehension, study, and diagnosis, because the classic neurological manifestations are easy to explain and understand if function and localization of affected anatomical structures are known as if the posterior cerebral circulation is.
