Introduction: Diabetes mellitus is a common disorder in Asian people occasionally presenting with unusual manifestations such as hemichorea-hemiballismus (HC-HB) is a rare manifestation of primary diabetes mellitus. Since chorea-ballismus can be life threatening, recognition of this disorder is important, because HC-HB caused by hyperglycemia is a treatable disorder with a good prognosis. Usually Hemichorea-Hemiballismus is induced by non-ketotic hyperglycemia; here we are reporting two cases of elderly women who presented as HC-HB induced by hyperglycemia with positive urine ketone bodies. We also described Computed Tomography (CT), Magnetic Resonance Imaging(MRI) findings in these two patients.
