Anterior Inferior Cerebellar Artery Infarct

According to the National Institute of Neurological Disorders and Stroke Wallenberg Syndrome aka Lateral Medullary Syndrome or Posterior Inferior Cerebellar Artery Syndrome is a neurological condition caused by a blockage of the vertebral artery VA or posterior inferior cerebellar artery PICA ultimately leading to infarction of the lateral medulla 1. Superior Cerebellar Artery origin from the PCA The apparent origin of the PCA from the P1 segment is in fact directly related to the embryology of the basilar artery which is formed by fusion of paired longitudinal neural arteries.

The hemorrhage of any of these arteries will result in facial paralysis on the side of hemorrhage and paralysis of limbs on the opposite side. This situation reflects relatively recent development of the neocortex in higher species Briefly the MCA arises from a phylogenetically far older anterior cerebral artery older because it vascularizes among. Left Cerebellar Infarct Cytotoxic edema in infarctions involves the gray and white matter therefore abnormal low attenuation extends to the cortex Important to know vascular territories. The clinical presentation of posterior circulation strokes can vary widely and depends on the location of the infarctPosterior circulation strokes commonly present with symptoms of altered mental status vision changes speech changes nystagmus vertigo ataxia limb weakness headache and a variety of other focal neurological deficits. It is characterized by sensory defects affecting the same side of the face as the infarct and the opposite side of the trunk as the infarct.

A syndrome caused by an infarct in the vertebral or posterior inferior cerebellar artery.

20 Affects the paramedian pontine reticular formation and. In the case of hemorrhagic events bleeding can directly damage tissue and worsen these deficits. B internal elastic lamina. Subsequent apical-lateral transmural Q wave myocardial infarction acute. The anterior inferior cerebellar artery that arises from the proximal part of the basilar artery is one of the 3 pairs of arteries that supply the cerebellumIt is ventrally related to the abducens facial and vestibulocochlear CN VIII nervesThe vessel takes a posterolateral course as it goes to supply the inferior aspect of the cerebellum. CT Scan to confirm the diagnosis.

The Middle Cerebral Artery is phylogenetically the youngest of all cerebral vessels see dedicated Neurovascular Evolution and Vascular Neuroembryology for more detail. Lateral medullary syndrome Wallenberg syndrome. Posterior circulation stroke syndrome POCS refers to the symptoms of a patient who clinically appears to have had a posterior circulation infarct but who has not yet had any diagnostic imaging eg. This is a posterior inferior cerebellar artery PICA infarct Acute to subacute stage of infarction can lead to mass effect from edema. Transient vision problems can likewise be a harbinger of stroke and prompt evaluation after recognition of visual symptoms can prevent future vascular injury. The blood vessels that reach the cerebellum are called the superior cerebellar artery the anterior inferior cerebellar artery and the posterior inferior cerebellar artery.

The circle of Willis consists of an arterial network located at the skull base allowing arterial blood flow exchange between the anterior and the posterior circulation and between the right and left hemispheres. Infarction of this artery may cause contralateral hemiparesis andor movement disorder potentially also with cognitive deficits. A Case Report Samantha Fisk. The superior cerebellar arteries SCAs arise distally from the basilar artery prior to its bifurcation into the posterior cerebral arteries PCAs. The wall of an artery consists typically of an outer coat tunica adventitia a middle coat tunica media and an inner coat tunica intima.
