[Gouty encephalopathy: myth or reality?].

Case report is a 75-year old woman who presented an unexplained febrile encephalopathy with diffuse myoclonic jerks and a gout's polyarthritis. None of these etiologies was found: infectious, toxic, vascular, metabolic, hormonal, immunologic. The spectacular effect on neurologic symptoms of a treatment by colchicine alone lead us to consider that gout encephalopathy probably exists.
