• A patient who had suffered a stroke showed crural paresis and pyramidal signs on one side, combined with severe cerebellar-like ataxia on the same side: the ataxic hemiparesis syndrome. Computed tomography disclosed sequential changes characteristic of a lacunar infarct in the superior portion of the posterior limb of the internal capsule adjacent to the corona radiata on the side opposite the neurologic deficit. This case study reinforces the possibility that a posterior capsular-corona radiata lesion can cause the ataxic hemiparesis syndrome.
