[Hemichorea, hemiballism disclosing non-ketotic hyperglycemia].
Non ketotic hyperglycemia is a metabolic disorder which can induce various hyperkinetic disorders. We report the case of a 74-year old woman admitted to hospital because of choreo-ballic movements of her left hemibody. Laboratory tests revealed non-ketotic hyperglycemia. CT scan showed an increased density in the right putamen and head of caudate. Magnetic resonance imaging disclosed a hyperintense signal involving the right putamen on T1-weighted images. On T2-weighted images, there was a slight hyperintensity in the right putamen and head of caudate. Correction of the underlying hyperglycemia led to complete resolution of abnormal movements. Pathophysiology of this clinicoradiologic syndrome is briefly discussed.
