We present distinctive MRI findings in an adult female patient with possible Sydenham's chorea. T2-weighted MRI showed bilaterally symmetric, diffusely homogenous, and clearly demarcated hyperintensities selectively involving the entire striatum with swelling of the bilateral caudate heads. The MRI features may reflect the pathogenetic mechanisms of Sydenham's chorea associated with a specific autoimmune response to the basal ganglia.
