Hemichorea without MRI findings accompanied by significant internal carotid artery stenosis: A case report

Abstract

Hemichorea is a clinical syndrome characterized by rapid, purposeless, irregular, and uncontrollable choreographic movements of the limbs and/or face, and it is frequently associated with cerebral infarction. We report here a case of acute hemichorea, as the first sign of severe stenosis of the contralateral terminal internal carotid artery without cerebral infarction, with complete remission after the endovascular intervention.
