![]() Lateral pontine syndrome is a neurological syndrome caused by occlusion of the anterior inferior cerebellar artery (AICA) and is characterized by crossed neurological signs and symptoms but also by ipsilateral deafness and facial paresis, in difference to the PICA-syndrome.The Weigert stain involves the treatment of nervous tissue with potassium dichromate to preserve myelin. Involving occlusion of posterior inferior cerebellar artery (PICA). Anatomically the infarcted area in Wallenberg syndrome is supplied by the posterior. The syndrome can also be due to occlusion of the vertebral artery, or the inferior, middle, or superior medullary vessels. Other signs and symptoms include vomiting, vertigo, hoarseness, dysphonia, dysphagia, decreased gag reflex, contralateral ataxia and ipsilateral Horner’s syndrome.(T/F?) (aka lateral medullary syndrome, PICA syndrome). Often associated with Wallenberg syndrome. The primary pathology of Wallenberg syndrome is occlusion of the posterior inferior cerebellar artery (PICA) or one of its branches (2).The syndrome is characterized by “crossed neurological signs”, ipsilateral sensory deficits of the face and contralateral sensory deficits of the trunk and the limbs.The posterior inferior cerebellar artery is a branch of the basilar artery and supplies lateral parts of the medulla oblongata and parts of the cerebellum with arterial blood. 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.1 This monograph highlights the neuro-ophthalmic presentations for the WS. WS is typically due to ischemia from a vertebral artery or posterior inferior cerebellar artery infarction. It is usually caused by occlusion of posterior inferior cerebellar artery, therefor the name PICA-syndrome. Wallenberg syndrome (WS) is a neurological disorder that is due to damage to the lateral portion of the medulla oblongata (i.e., the lateral medullary syndrome).Lateral medullary syndrome or Wallenberg syndrome is caused by occlusion of the arteries that supply lateral medulla oblongata. ![]()
