A Case of Pediatric Guillain-Barré Syndrome After Respiratory Syncytial Virus Infection.

We report a two-year-old girl whose progressive lower extremity weakness was masked by a respiratory presentation, only to be identified as having Guillain-Barré syndrome in the context of respiratory syncytial virus bronchiolitis. This case adds to the expanding literature of postinfectious demyelinating disorders in very young children, which seem to be unrelated to particular antigenic triggers.
