Lateral Medullary Infarct usually result from occlusion of the vertebral artery or posterior inferior cerebellar artery.
A stroke in the lateral medulla results in a Wallenberg's syndrome, manifested by nausea, vomiting, and vertigo along with ipsilateral facial numbness, weakness of the ipsilateral soft palate, ipsilateral ataxia, and contralateral numbness of the body.
