Vasculitic neuropathy mimicking Guillain-Barré syndrome.

Vasculitic neuropathy classically manifests as a subacute mononeuritis multiplex or polyneuropathy. Patients with a Guillain-Barré syndrome (GBS)-like presentation are usually not considered to have an underlying vasculitis. We describe 2 patients with rapidly progressive areflexic paralysis that was initially diagnosed as GBS, in whom vasculitic neuropathy was found histologically.
