ABSTRACT
CASE PRESENTATION A 32-year-old woman with a history of developmental delay was admitted to hospital for subacute adenopathy, arthritis, fever, and tongue ulcerations. Shortly after admission, she developed severe chorea of the extremities, head, and trunk. She had no prior history of a movement disorder, recent bacterial infection, or exposure to dopamine-receptor blocking agents. There was no history of tobacco, alcohol, or illicit drug use and she was not taking any medications. Family history was significant for a maternal aunt with systemic lupus erythematosus.
