A 16-mo-old girl is described with acute hemiplegia associated with virologic and serologic evidence of Coxsackie A9 infection. Possibilities of pathogenesis are discussed. It is suggested that the present hemiplegia may have been the result of a focal vasculitis due to Coxsackie A9 viral infection in the region of the right middle cerebral artery.
