title: Sydenham's chorea: positron emission tomographic (PET) scan studies.
abstract: Two patients with Sydenham's chorea were evaluated with positron emission tomographic (PET) scans in the active phase of the disease. One patient had repeat scanning in the recovery phase. PET scans showed hypermetabolic changes of the caudate nuclei and putamen in the active phase of Sydenham's chorea. The scan reverted to normal in the recovery phase. These changes can afford a basis for comparing concurrent serum antibody studies in the acute and recovery phases of Sydenham's chorea.
