Abstract

We report on an autopsy findings of a 92-year-old male with hemiballism-hemichorea associated with hyperglycemia and striatal hyperintensity on T1-weighed magnetic resonance imaging (MRI), a recently described clinicoradiological syndrome. Histologically, the putamen contralateral to the hemiballism consisted of multiple foci of recent infarcts associated with reactive astrocytic and interneuronal response. Substrate responsible for the MRI signal changes is still inconclusive. © Movement Disorder Society.
