Guillain-Barré syndrome presenting with severe musculoskeletal pain.

Three children with Guillain-Barré syndrome are described who presented with musculoskeletal pain to an orthopaedic clinic or to a paediatric rheumatologist at a children's hospital. In each case, osteomyelitis of the spine was considered to be the most likely diagnosis and bone scans were performed in two of the three patients. Two of the three children required care in an intensive care unit, within hours of diagnosis. Outside of the specialty of neurology, the presentation of Guillain-Barré syndrome with severe muscle pain is not generally well known. With greater awareness of this particular presentation, dangerous delays in diagnosis and inappropriate investigations will be minimized.
