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.

Sep 8, 2024 · The PICA (posterior inferior cerebellar artery) is the most common stroke that causes dizziness PICA (posterior cerebellar artery syndrome). AKA "lateral medullary syndrome" (LMS), or "Wallenberg's syndrome"

Jan 14, 2025 · Posterior inferior cerebellar artery (PICA) occlusion may cause infarction of any part of the vascular territory of the PICA, namely the posterior inferior cerebellum, inferior cerebellar vermis, and lateral medulla.

The posterior inferior cerebellar artery (PICA), with its unique anatomical complexity, is of great clinical importance and involved in many diseases including aneurysm, ischemic stroke, neurovascular compression syndrome (NVCS), arteriovenous ...

Wallenberg syndrome = Lateral medullary syndrome (aka 'PICA' syndrome Posterior Inferior Cerebellar Artery syndrome) Constellation of neurologic symptoms due to injury to the lateral part of the medulla in the brain. Sensory deficits affecting the trunk (torso) and extremities on the opposite side of the infarction

PICA termination of VA (PICA-VA) is occasionally found on routine brain magnetic resonance angiography (MRA); however, only a few studies to date have reported the prevalence of this vascular variant.

Mar 19, 2023 · Posterior inferior cerebellar artery (PICA) is one of the three vessels that provide arterial supply to the cerebellum. It is the most variable and tortuous cerebellar artery.

The most common cause of Wallenberg Syndrome is an ischemic stroke in the VA or PICA of the brainstem, often the result of a thrombus or embolism. Dissection of the VA following mechanical trauma or head injury is a second important risk factor and is more common in younger patients.

Mar 4, 2025 · Named after Adolf Wallenberg in 1895, this neurological condition is characterized by lateral medullary infarction resulting from an occlusion of the posterior inferior cerebellar artery (PICA) or the vertebral artery.

Most strokes cause weakness on one side of the body. Some strokes affect the brainstem and cerebellum. The Posterior Inferior Cerebellar Artery (PICA) carries blood to this part of the brain. This stroke (Wallenberg’s Syndrome) causes the person to …
