Abstract:
Diabetic non-ketotic bilateral chorea is a rare complication of diabetes. This article reports an elderly female patient with a history of diabetes who suddenly developed bilateral choreiform involuntary movements. Laboratory tests indicated elevated blood glucose levels and negative ketone. Cranial magnetic resonance imaging showed high signal intensity on T 1-weighted images in the right basal ganglia and left thalamus regions, and computed tomography scan of the head indicated high-density shadows in the right basal ganglia region. The diagnosis of diabetic non-ketotic bilateral chorea was considered. After active hypoglycemic control and symptomatic treatment for involuntary movements, the choreiform involuntary movements were relieved. Through literature review, the case characteristics, diagnosis, treatment, and pathogenesis of patients with diabetic non-ketotic chorea are summarized, aiming to enhance clinicians′ understanding of this disease and avoid misdiagnosis and missed diagnosis.
