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. Lateral Medullary Syndrome (Wallenberg): Contralateral hemibody pain/temp loss [Ipsilateral CN 9, 10] Ipsilateral dysphagia (hoarsness) loss gag reflex vertigo diplopia and nystagmus Ipsilateral Horner's Syndrome Ipsilateral loss of facial pain and temperature Ipsilateral ataxia
Wallenberg Syndrome is when you damage blood supply to the LATERAL medulla (i.e. PICA) 1) You damage your Nucleus ambigus: pt will complain of dysphasia, dysarhria 2) Damage the Trigeminal nerve (note the trigeminal nucleus is in the pons but the pathway continues down the spinal cord so you'll find some fibers in the medulla laterally).

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
Wallenberg syndrome (lateral medullary syndrome/stroke) refers to a cerebrovascular occlusion that occurs in either the vertebral artery or the posterior inferior cerebral artery (PICA). This condition is often caused by thrombosis or embolism, however other causes such as syphilitic arteritis and vertebral artery dissection are also possible. Wallenberg syndrome, also known as “lateral medullary syndrome” or “ posterior inferior cerebellar artery (PICA) syndrome”, is the most prevalent posterior ischemic stroke syndrome. 1.
