Diabetic chorea (DC) is a rare complication of diabetes. Here we describe two cases of DC; patient 1 was an 87-year-old woman with chronic kidney disease and was administered with sulphonylurea and dipeptidylpeptodase-4 inhibitor. She showed right side hemiballismus and head magnetic resonance imaging T1-weighted images revealed a high intensity area in the putamen and caudate nucleus. Patient 2 was a 51-year-old woman who was diagnosed with diabetic ketoacidosis. She showed right side hemiballism and multiple, small hyperintense regions in both the periventricular sides in diffusion weighted images. Based on the hemiballism, we concluded a diagnosis of DC in the diabetic patient, although the case presentation is rare or has atypical MRI findings.
