We report a patient with an acute neuropathy initially mimicking Guill
ain-Barre syndrome, both clinically and electrophysiologically. Persis
tent eosinophilia, positive antineutrophil cytoplasmic antibody and eo
sinophilic vasculitis in sural nerve biopsy later confirmed Churg-Stra
uss syndrome. Since vasculitic neuropathy can present in an acute and
fulminant form, the role of early antibody testing and sural nerve bio
psy in atypical cases af acute neuropathy is emphasized.
