Wallenberg's syndrome

Wallenberg's syndrome is the clinical manifestation of an infarct[?] located in the lateral medulla[?], characterized by sensory deficits affecting the trunk and extremities on the opposite side of the infarct and sensory and motor deficits affecting the face and cranial nerves on the same side with the infarct. Other clinical symptoms and findings are ataxia, facial pain, vertigo, nystagmus[?], Horner's syndrome[?], diplopia[?] and dysphagia. The cause of this syndrome is usually the occlusion of the posterior inferior cerebellar artery (PICA) at its origin.
