Hemichorea induced by nonketotic hyperglycemia is a rare complication of diabetes mellitus. It is characterized by the triad of unilateral involuntary choreiform movements, hyperglycemia without ketosis, and hyperintensity of contralateral basal ganglia on nuclear magnetic resonance images mainly on T1 or high density on CT scans. It has a high potential for total or partial recoverability of its clinical expression, for this reason timely diagnosis and treatment is essential to avoid irreversible neurological sequelae. Two clinical cases of this syndrome are presented, in which the inconsistency of the imaging findings with the clinical ones is striking.

Keywords : chorea; diabetes mellitus; basal ganglia; hyperglycemia; nuclear magnetic resonance.
