Introduction Hemichorea-hemiballismus, secondary to hyperglycemia, is a rare but easily treatable condition that is usually associated with poorly controlled type II diabetes mellitus. Diagnosis is based on clinical assessment and imaging. Etiology includes primarily cerebrovascular diseases, metabolic, degenerative, infectious diseases, space-occupying lesions, basal ganglia damage due to drugs and toxic substances.

Case Here we report a rare case of a 78-year-old woman presenting with involuntary movements on the left side of her body secondary to long standing and uncontrolled hyperglycemia. The T1-weighted magnetic resonance imaging revealed hyperintensity in the right basal ganglia. She received intensive insuline therapy and haloperidol. During the follow-up, the patient’s blood glucose level and HbA1c improved, along with significant improvement in choreiform movements.

Conclusion In conclusion, when patients with diabetes mellitus present with unilateral movement disorder, non-ketotic hyperglycemic chorea should be considered, and treatment should be started immediately after diagnosis.

Key Words: Hemichorea, Hemiballismus, Hyperglycemia, T-1 hyperintensity.
