Acute-onset chorea in the pediatric population is most commonly associated with Sydenham chorea, which is a manifestation of acute rheumatic fever. Chorea is a much less commonly noted sign of stroke, and when it occurs, it typically presents as hemichorea. Given the unlikely presentation, rapid and appropriate imaging was the key to diagnosis.
