Cressman S, Rheinboldt M, Lin D, and Blasé J. Nonketotic hyperglycemia-induced hemichorea-hemiballism. Appl Radiol 2018; 47(6):24-26.
A 57-year-old woman presented to the emergency department complaining of headache, nausea and vomiting. Relevant medical history included hypertension and insulin dependent type 2 diabetes with poor to nonexistent medical compliance over the preceding year. Headaches were intermittent by patient report with accompanying vague reported coordination loss in the left upper extremity. Review of systems was positive for mild dysmetria in the left upper extremity. Blood glucose levels were elevated at 574 mg/dl, but secondary laboratory findings were negative for diabetic ketoacidosis. Blood pressure, glucose control and supportive care was initiated. The patient’s symptomatology normalized with supportive care and the subsequent short hospital course and discharge were uneventful.
