{Reference Type}: Case Reports {Title}: Hemichorea-hemiballismus due to diabetic striatopathy a serious complication of uncontrolled diabetes. {Author}: Middleton B;Albany Z;Kamer A;Kara A; {Journal}: BMJ Case Rep {Volume}: 17 {Issue}: 5 {Year}: 2024 May 22 暂无{DOI}: 10.1136/bcr-2023-259046 {Abstract}: We report the case of a man in his mid-80s with diabetes mellitus who presented to the emergency department with a 1-day history of right-sided choreiform movements and falls. Laboratory tests revealed blood glucose of 597 mg/dL. Non-contrast CT imaging of his head demonstrated a faint hyperdensity involving the left lentiform nucleus and brain MRI showed a hyperintensity in the left basal ganglia on T1-weighted images. These lesions are typical of diabetic striatopathy. Symptoms of hemichorea/hemiballismus did not resolve with glycaemic control and several pharmacological agents were tried with eventual improvement with risperidone. He was discharged to a rehabilitation facility and had mild persistent arm chorea at 6-month follow-up.
