A Case Report and Literature Review of Nonketotic Hyperglycemic Hemichorea.

ABSTRACT

Nonketogenic hyperglycemic hemichorea, also recognized as diabetic striatopathy, is a rare manifestation of diabetes mellitus. The diagnosis of nonketotic hyperglycemic hemichorea is usually made through imaging along with a corresponding clinical picture. Early identification and treatment can lead to complete resolution of the symptoms and better patient outcomes. Here we present a 49-year-old female patient, with a past medical history of poorly controlled type 2 diabetes mellitus and prior left index finger amputation as a complication of her diabetes, who presented for evaluation of a two-week duration of sudden-onset left upper extremity choreiform movements.
