Abstract
Guillain-Barré syndrome (GBS) and Miller Fisher syndrome (MFS) are acute immune-mediated peripheral neuropathies. In addition to their classic presentations, a variety of other signs and symptoms have been reported; however, headache appears to be relatively uncommon. We describe a 53-year-old woman who presented with acute bulbar palsy as the first symptom of overlapping MFS/GBS accompanied by severe headache. The first important clinical impairment of the patient was acute bulbar palsy along with prominent headache, without limb weakness. Although her initial diagnosis was acute bulbar palsy plus, she subsequently developed lower limb diffuse weakness, and her final clinical diagnosis was overlapping MFS/GBS. Anti-ganglioside antibodies were positive for anti-GQ1b and anti-GT1a immunoglobulin G. The patient received intravenous immunoglobulin on day 2 of admission. Early identification of these overlapping syndromes is important for the management of patients, to avoid respiratory failure or severe weakness with axonal degeneration. We therefore remind clinicians of the importance of further examination in patients with headache and acute bulbar palsy of unknown origin.
