Spontaneous hemiballism and disappearance of parksinsonism following contralateral lenticular lacunar infarct.
Hemiballism was observed in a 77-year-old woman with Parksinson disease after a contralateral lenticular infarct without apparent involvement of the subthalamic nucleus. Parkinsonian signs ipsilateral to the hemiballism remained abolished despite subsequent nearly complete recovery from the hyperkinesias. It is argued that clinical events were due to a single ischemic lesion of the putamen-pallidum complex.
