title: Encephalomyeloneuritis simulating Guillain-Barré syndrome.
abstract: A patient with encephalomyeloneuritis (EMN) had clinical and laboratory features consistent with severe acute inflammatory polyneuropathy (Guillain-Barré syndrome). CNS involvement was suggested clinically only by transient downbeat nystagmus and by contraction of tensor fascia lata on plantar stimulation. Postmortem examination revealed pathologic changes typical of EMN without systemic neoplasm. Clinical manifestations of the profound central pathology were largely obscured by severe radiculoneuropathy. Pathologic verification of clinically diagnosed inflammatory polyneuropathy is unusual, and CNS disease, therefore, may be more frequent than appreciated, especially in clinical "variants."
