The goal of treatment is to reduce the size of infarction and prevent medical complications. Rapid evaluation is an essential component in improving the patientвЂ™s clinical outcome and prognosis. The management of Wallenberg syndrome is similar to the management of any acute stroke. Patients with a suspected diagnosis should undergo MRI evaluation, including diffusion-weighted imaging, which is the best tool to confirm the infarct in the inferior cerebellar area or lateral medulla. Ataxia, nystagmus, Horner syndrome, and damage to the spinal trigeminal nucleus causes absence of pain and temperature sensation on the ipsilateral side of the face, as well as a diminished corneal reflex. Physical examination reveals sensory and motor deficits affecting the face and cranial nerves on the ipsilateral (same) side of the infarct. Like most ischemic stroke syndromes, initial diagnosis is usually suspected from the patientвЂ™s clinical characteristics upon physical examination. In younger people, the most common cause of Wallenberg syndrome is vertebral artery dissection. Other, less common, risk factors include connective tissue disorders, such as Marfan syndrome, EhlersвЂ“Danlos syndrome, and fibromuscular dysplasia. The most common risk factors for Wallenberg syndrome include hypertension ( high blood pressure), smoking, and diabetes.

Other symptoms include dizziness, double vision, pain or loss of pain on one side of the face, loss of taste on one side of the tongue, difficulty swallowing, slurred speech, and hoarseness. Another frequent finding is Horner syndrome, which is characterized by decreased pupil size, drooping eyelid, and decreased sweating on one side of the body. Typically, this is due to an atherothrombotic occlusion, which is when a blood clot blocks one of the arteries that supply the medulla.Common symptoms include ipsilateral palate weakness, impaired coordination, and contralateral sensory disturbances that involve the contralateral trunk and extremities, and can cause impaired gait and falls.

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. Wallenberg syndrome, also known as вЂњ lateral medullary syndromeвЂќ or вЂњ posterior inferior cerebellar artery ( PICA) syndromeвЂќ, is the most prevalent posterior ischemic stroke syndrome.
