A Child with Raccoon Roundworm Meningoencephalitis: A Pathogen Emerging in your Own Backyard?

Abstract

Raccoon roundworm (Baylisascaris procyonis) is a cause of devastating neural and ocular disease. The first documented case of raccoon roundworm encephalitis in Canada, in a seven-year-old boy who presented with severe neurological impairment, is presented. His significant recovery illustrates the importance of clinical suspicion and the benefit of early treatment.
