Diabetic chorea (DC) is a rare complication of diabetes. Here we describe two\ncases of DC; patient 1 was an 87-year-old woman with chronic kidney disease\nand was administered with sulphonylurea and dipeptidylpeptodase-4 inhibitor.\nShe showed right side hemiballismus and head magnetic resonance imaging\nT1-weighted images revealed a high intensity area in the putamen and\ncaudate nucleus. Patient 2 was a 51-year-old woman who was diagnosed with\ndiabetic ketoacidosis. She showed right side hemiballism and multiple, small\nhyperintense regions in both the periventricular sides in diffusion weighted\nimages. Based on the hemiballism, we concluded a diagnosis of DC in the diabetic\npatient, although the case presentation is rare or has atypical MRI\nfindings.
