Abstract
<p>We herein report an 84-year-old woman with right middle cerebral artery (MCA) stenosis who presented with persistent left hemichorea preceding cerebral infarction. She visited our hospital on day 9 after the hemichorea onset. Magnetic resonance imaging (MRI) showed no acute cerebral infarction. Magnetic resonance angiography revealed right MCA stenosis. Her hemichorea persisted for 19 days and subsequently disappeared. On day 21, she developed left hemiplegia. Repeat MRI revealed a cerebral infarction in the right putamen. MCA stenosis can present with persistent hemichorea, even in the absence of cerebral infarction. Persistent hemichorea with MCA stenosis may presage cerebral infarction. </p>
