Abnormal motor behaviors caused by ipsilateral hemispheric lesions have not been frequently reported. However, a 76-year-old woman developed left hemiparesis and abnormal movements of the right limb. Upon observation, she would unintentionally rotate her hand continuously on the table in a stereotypical way. A brain CT showed an infarction in the basal ganglia and corona radiata. We report this patient with unilateral hyperkinesia and contralateral hemiparesis due to ipsilateral basal ganglia lesions.
