Hemichorea-hemiballism and lacunar infarction in the basal ganglia.
We present a case of acute hemichorea-hemiballism associated with lacunar infarct documented by computerized tomography scan in the contralateral putamen and caudate nuclei. The pathoanatomic data of similar cases in the literature are reviewed with reference to the location of the responsible lesions. Acute hemichorea-hemiballism is most frequently caused by lacunar infarcts in the basal ganglia contralateral to the dyskinesia.
