Abstract

A 71-year-old man with a 5 to 6-year history of poorly controlled type 2 diabetes mellitus was admitted for involuntary movement (hemichorea) of the right upper and lower extremities.Plasma glucose was 456-767mg/dl, and HbA1c 13.8%. Magnetic resonance imaging (MRI) showed hyperintensity on T 1-weighted images in the left putamen and caudate nucleus.Involuntary movements were resolved in l month when plasma glucose was corrected by diet and oral medication. After discharge, hyperglycemia recurred and poor diabetic control persisted. Eight months later, he was readmitted with hyperglycemia, and his plasma glucose was 515mg/dl and HbA1c 12.1%. On the second admission, involuntary movement recurred in the right leg. His diabetic hemichorea-hemiballism was thus a novel diabetic complication.
