Hyperglycemic Nonketotic Hemichorea-Hemiballismus- A Case Report with Review of Literature

Abstract

Hemichorea-hemiballismus can rarely present in nonketotic hyperglycemia. Elderly aged women after attaining menopause can have this as a first presentation. We reported a case of 70-year-old women presented with loss of consciousness, hemiballismus and hemichorea associated with non-ketotic hyperglycemia. CT imaging of brain reveals no abnormality. MRI was done when patient was having the hemichorea and hemiballismus which it showed hyperintense signal on T1WI, hypointense signal on T2WI involving the putamen region of lentiform nucleus on left side. Her symptoms were not seen after correction of serum glucose value to normal level. In our case we can notice the significance of detecting rare findings which shows in diabetic patients and to differentiate by using MRI from other common pathologies causing neurological symptoms.
