Wallenberg Syndrome: What Is It, Causes, Diagnosis

  1. Wallenberg syndrome, also known as lateral medullary syndrome or posterior inferior cerebellar artery (PICA) syndrome, is the most prevalent posterior ischemic stroke syndrome
  2. LMS, also named Wallenberg syndrome or posterior inferior cerebellar artery syndrome, is due to damage to the lateral part of medullary oblongata caused by vascular events. The most frequently involved vessels are the PICA or the VA [111, 112]. LMS is the most prevalent posterior circulation ischemic stroke syndrome and is the typical presentation of PICA territory infarcts
  3. Headache and neck pain is normally the result of full posterior inferior cerebellar artery territory infarcts and is likely secondary to the associated swelling and mass effect 3. There are multiple eponymous posterior stroke syndromes, often presenting incompletely 4
  4. The posterior inferior cerebellar artery (PICA) has a variable and tortuous (with multiple loops) course within the posterior cranial fossa; such variability accounts for the variable relationship that CN IX has to XII. Most often, the PICA originates from the vertebral artery and has its first loop upward
  5. 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
  6. A severe occlusion of the posterior inferior cerebellar artery (PICA) can lead to the lateral medullary syndrome also known as the Wallenberg syndrome. It causes sensory, muscular dysfunction in the trunk and extremities on the opposite side of the occluded artery

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. Gross anatomy Origin Its origin is highly variable: ~20% arise ext.. Posterior cerebral artery syndrome is a condition whereby the blood supply from the posterior cerebral artery (PCA) is restricted, leading to a reduction of the function of the portions of the brain supplied by that vessel: the occipital lobe, the inferomedial temporal lobe, a large portion of the thalamus, and the upper brainstem and midbrain Wallenberg syndrome also known as lateral medullary syndrome or the posterior inferior cerebellar artery syndrome, is a neurological disorder is associated with a variety of symptoms that occur as a result of damage to the lateral segment of the medulla posterior to the inferior olivary nucleus 1).

The most common causes of posterior circulation large artery ischemia are atherosclerosis, embolism, and dissection. Dolichoectasia (elongation and tortuosity) of the vertebral and basilar arteries is another occasional cause. About one-third of posterior circulation strokes are caused by occlusive disease within the large neck and intracranial. The blood supply affected is the pontine perforating arteries, branches of the basilar artery, anterior inferior cerebellar artery, or the superior cerebellar artery. One-and-a-half syndrome: Affects the paramedian pontine reticular formation and medial longitudinal fasciculus. It results in the ipsilateral conjugate gaze palsy and internuclear.

RANGIAH Fromthe Institute ofVenereology, Government GeneralHospital, Madras, India The syndrome of occlusion of the posterior inferior cerebellar artery was first described by Wallenberg (1895). Since his first description, Lateral Medullary Syndrome ( C0043019 ) A syndrome caused by an infarct in the vertebral or posterior inferior cerebellar artery. 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. Patients experience difficulty swallowing and/or speaking The posterior cerebral artery PCA is one of a pair of arteries that supply oxygenated blood to the occipital lobe, part of the back of the human brain arteries and thus are connected to the anterior cerebral arteries and the posterior communicating arteries which connect to the posterior cerebral arteries communicating artery Anterior cerebral artery syndrome refers to symptoms that follow a.

Clinically, it is difficult to differentiate this syndrome from the posterior inferior cerebellar artery syndrome and the anterior inferior cerebellar artery syndrome. The diagnosis is confirmed with MRI. This disease results in: Contralateral loss of touch and pain sensation from the body; Nausea and vomiting; Slurred speech; Cerebellar ataxia The posterior inferior cerebellar artery (PICA) sometimes supplies the lateral medullary area.'2 Its occlusion may then result in Wallenberg's syndrome.34 Whenthe PICA does not supply the medulla, its occlusion maylead to a pure vertigo, with or without associated cerebellar signs.9 Syn-*dromes resulting from the occlusion of the medialorthe. Wallenberg syndrome (Lateral medullary syndrome) is a rare neurological syndrome, caused by a stroke in the vertebral artery or its largest branch- posterior inferior cerebral artery (PICA) [1,2]. PICA is one of the 3 major arteries that provide blood supply to Cerebellum. The syndrome involves many important structures in the cerebellum. 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. Occlusion of the posterior inferior cerebellar artery or one of its branches, or of the vertebral artery leads to lateral medullary syndrome also called Wallenberg.
