MRI of the brain of a 3-year-old boy performed 3 days after the onset of hemichorea (Sydenham Chorea) revealed abnormal signal and enlargement of the contralateral caudate and putamen. Follow-up imaging 40 months later showed a persistent cystic appearance of the caudate and putamen. This case is the first report of permanent MRI abnormalities after Sydenham Chorea.
