Abstract

Hemibalplismus is regularly associated with lesions in the contralateral subthalamic nucleus. In addition, hemichorea, at times violent enough to be called hemiballismus, occurs occasionally as a result of lesions in other sites, including the pallidum, thalamus, cortex, and, most often, the neostriatum, usually on the side opposite the uncontrollable limbs. We describe a patient in whom two distinct episodes of severe left-sided hemichorea were associated with two separate right-sided cerebral lesions, one chiefly in the putamen, the second in the caudate nucleus.
