[Acute polyradiculoneuritis and toxoplasmosis]

A patient developed acute polyradiculoneuritis during the course of a recent infection due to toxoplasma. A cause/effect relation is discussed and appears likely. A review of 3 published cases failed to determine any specific clinical features of the polyradiculoneuritis. Serology for toxoplasmosis should be included in the etiologic investigations of apparently primary Guillain-Barré's syndrome.
