Abstract
-
Hemichorea or hemiballism has been correlated clinico-anatomically with lesions of the contralateral side, most commonly of the subthalamic nucleus. Hemichorea due to an ipsilateral lesion is extremely rare. We report a case of a 74-year-old man who developed a left sided hemichorea due to a left thalamic infarction. The literature on the rare occurrence of ipsilateral hemichorea/hemiballism is discussed and possible pathomechanisms are reviewed.
