Reversible acute chorea in a patient with diabetes treated with hemodialysis

Abstract

Chorea is an abnormal hyperkinetic movement disorder. The reasons for chorea are diverse and include hereditary, endocrine, toxic, vascular, infectious, autoimmune, and metabolic etiologies. We present a 64-year-old woman with acute chorea who suffered from diabetes with recurrent hypoglycemia, and chronic renal failure treated by hemodialysis. The full clinical recovery, negative work-up and disappearance of basal ganglia lesions on the follow-up imaging emphasize the transient character of encephalopathy expressed by acute chorea in patients with diabetes treated with hemodialysis.
