[A case of adult-onset Sydenham chorea accompanied with psychiatric symptoms].
We report a 56-year-old man with adult-onset Sydenham chorea. Since January 2003, he had often troubled other persons, and in October 2003, following an episode of fever in August of the same year, he noticed left shoulder joint pain and involuntary movements of his limbs, especially on the left side. These involuntary movements gradually worsened and he became unable to converse due to psychiatric symptoms. On admission, neurological examination revealed dementia, emotional incontinence, abnormal behavior and chorea in four limbs. Brain MRI disclosed swelling of bilateral caudate heads that was more marked on the right side. Hypermetabolism in bilateral caudate nuclei, especially on the right, was found on FDG-PET study, which was compatible with his left side-dominant chorea and might reflect inflammation as a nature. A gallium scintigram demonstrated excess accumulations in the plural joints of his extremities, which gradually decreased in parallel with joint pain relief. The present case was diagnosed as Sydenham chorea, because of the presence of arthritis, chorea, fever, increased erythrocyte sedimentation rate and elevated CRP. We believe that this is a first report of adult-onset Sydenham chorea accompanied with psychiatric symptoms.
