title: Acute onset of chorea and dystonia following a febrile illness in a 1-year-old boy.
abstract: A 12-month-old boy with acute onset hemichorea and dystonia following a gastroenteritis has abnormal signal intensities of his basal ganglia on brain magnetic resonance imaging (MRI). A rigorous laboratory investigation is successful in diagnosing his rare condition. A discussion of the differential of abnormal basal ganglia on MRI is presented to help illustrate this case.
