Asymmetric pharyngeal-cervical-brachial weakness associated with anti-GT1a IgG antibody

Osaki Y, Koga M, Matsubayashi K, Yuki N. Asymmetric pharyngeal–cervical–brachial weakness associated with anti-GT1a IgG antibody. Acta Neurol Scand 2002: 106: 234–235. © Blackwell Munksgaard 2002. We report a case of markedly asymmetric pharyngeal–cervical–brachial weakness. Acute progression of symptoms, albuminocytologic dissociation in cerebrospinal fluid, electrophysiologic evidence of demyelination and elevation of IgG anti-GT1a antibody titer paralleled the clinical course, support the diagnosis of Guillain–Barre syndrome. Guillain–Barre syndrome should be considered in the differential diagnosis of cranial neuropathy, even in cases where there is marked asymmetry.
