Abstract

Hemichorea have been reported in patients with nonketotic hyperglycemia. Usually, hemichorea and hyperglycemia are concomitant. A 73-year-old woman was admitted for investigation of an acute hemichorea. T1-weighted brain magnetic resonance imaging showed hyperintensity in the right putamen. Although she was a diabetic patient, she had no hyperglycemia. Interestingly, 4 weeks earlier, the patient was admitted due to nonketotic hyperglycemia. However, there were no hemichorea at that time. Although pathophysiologically controversial, a delayed hemichorea without nonketotic hyperglycemia should be considered as one of many different causes when evaluating acute hemichorea in diabetic patients.
