We report 3 diabetic patients who developed hemiballism without involvement of the subthalamic nucleus. Each patient exhibited vigorous, flinging, ballistic involuntary movements in the extremities and slight facial grimacing involving one side of the body. Although diabetes was poorly controlled in all 3, each patient was nonketotic at the onset of hemiballism. Magnetic resonance imaging (MRI), in these patients showed abnormalities in the striatum contralateral to the hemiballism that were… CONTINUE READING
