Pure Limb Ataxia as Isolated Manifestation in Lateral Medullary Infarction

Pure limb ataxia without other common symptoms of Wallenberg syndrome has rarely been reported as manifestation of lateral medullary infarction. We describe a patient with lateral medullary infarction who presented with almost isolated right limb(mainly lower limb) ataxia without usual symptoms such as hemibody sensory changes, dysphagia, hoarseness, hiccup, and Horner sign. The brain magnetic resonance image showed small ischemic lesion involving the dorsolateral portion of the medulla oblongata.
