It can be caused by an interruption to the blood supply of the anterior inferior cerebellar artery.

The arterial supply of these plexus is from posterior inferior cerebellar artery.

Inferior cerebellar arteries can refer to:

The posterior spinal artery can often originate from the posterior inferior cerebellar artery, rather than the vertebral.

A stroke that cuts off the blood supply to this area (e.g., a clot in the posterior inferior cerebellar artery) destroys both tracts simultaneously.

Posterior inferior cerebellar artery (PICA)

Anterior inferior cerebellar artery (AICA)

The anterior inferior cerebellar artery (AICA) is an artery in the brain that supplies part of the cerebellum.

Occlusion of the posterior inferior cerebellar artery or one of its branches, or of the vertebral artery leads to Wallenberg syndrome, also called lateral medullary syndrome.

Lateral medullary syndrome, also known as Wallenberg's Syndrome, is caused by blockage of the posterior inferior cerebellar artery (PICA) or the vertebral arteries.

The posterior inferior cerebellar artery (PICA), the largest branch of the vertebral artery, is one of the three main arterial blood supplies for the cerebellum, part of the brain.

Lesions of the posterior inferior cerebellar artery (PICA) lead to the so called lateral medullary syndrome, with ipsilateral Horner's Syndrome as the result of lesioning this nucleus.

The spinothalamic tract is spared because it is located more laterally in the brainstem and is not supplied by the anterior spinal artery, but rather by the vertebral and posterior inferior cerebellar arteries.

From the basilar artery arises the anterior inferior cerebellar artery (supplying the superior and inferior aspects of the cerebellum), as well as smaller branches for the supply of the pons (the pontine branches).

It is the clinical manifestation resulting from occlusion of the posterior inferior cerebellar artery (PICA) or one of its branches or of the vertebral artery, in which the lateral part of the medulla oblongata infarcts, resulting in a typical pattern.

Cerebellar stroke syndrome is a condition in which the circulation to the cerebellum is impaired due to a lesion of the superior cerebellar artery, anterior inferior cerebellar artery or the posterior inferior cerebellar artery.

Posterior inferior cerebellar artery (PICA): The posterior inferior cerebellar artery, a major branch of the vertebral artery, supplies the posterolateral part of the medulla, where the main sensory tracts run and synapse.

Lateral medullary syndrome (also called Wallenberg syndrome and posterior inferior cerebellar artery syndrome) is a disease in which the patient has a constellation of neurologic symptoms due to injury to the lateral part of the medulla in the brain, resulting in tissue ischemia and necrosis.
