Síndrome de hemicorea hemibalismo secundario a estriatopatía diabética

Abstract

Introduction

Hyperkinetic abnormal movements include chorea, dystonias, myoclonus, tremor, ballismus, and tics, and may be secondary to various treatable causes, such as metabolic disorders. Hemichorea-hemiballismus syndrome is a rare manifestation in patients with type 2 diabetes mellitus and poor metabolic control.

Case presentation

We report the case of a 67-year-old woman with long-standing type 2 diabetes mellitus and glycated hemoglobin of 19%, who presented hyperkinetic movements in the left side of the body. Magnetic resonance imaging showed T1 hyperintensity of the right putamen, compatible with metabolic striatopathy. The patient improved after glycemic control and treatment with haloperidol.

Conclusion

Hyperglycemia-induced dyskinesia is a reversible condition with adequate metabolic control. It is essential to recognize this entity to avoid unnecessary studies and optimize therapeutic management.
