Background: Sydenham's chorea, a major manifestation of rheumatic fever, is characterized by chorea, behavioral changes, and cognitive dysfunction. Perfusion changes in the basal ganglia are the most frequent imaging findings observed in patients with Sydenham's chorea.

Methods: Twelve adult women with Sydenham's chorea in remission underwent brain single-photon emission computed tomography (SPECT).
