Capsular Hypesthetic Ataxic Hemiparesis Stroke 21:24-33, Helgason,C.M.&Wilbur,A.C., 1990 See this aricle in Pubmed Article Abstract Twenty-three patients with hypesthetic ataxic hemiparesis underwent computed tomography or magnetic resonance imaging.Twenty-two patients had infarcts of lacunar or slightly larger size in the contralateral posterior limb of the internal capsule.In 15 patients the infarct extended superiorly into the adjacent paraventricular region,and in seven it extended into the lateral thalamus.In eight patients the infarct was limited to the posterior limb of the internal capsule,and in only two patients was an ipsilateral to capsular pontine lacune found.Despite a location similar to that of pure motor and pure sensory lacunar stroke, hypesthetic ataxic hemiparesis correlates with larger infarcts,most often located in the posterior medial superior territory of the anterior choroidal artery.Some infarcts appeared to be localized immediately posterolateral to this region,in the posterior cerebral artery territory. The presence and extent of infarction is better detected by the addition of magnetic resonance imaging to computed tomography.
