Polyradicular neuritis and Hashimoto's thyroiditis.

The case of a patient with a pluripotential immuneproliferative syndrome is reported. She suffered from Hashimoto's thyroiditis with secondary cold agglutination disease and from polyradicular neuritis. Polyradicular neuritis with albumino-cytological dissociation in the CSF had developed chronically and improved only when corticosteroid therapy was begun. Based on this case report fundamental considerations concerning the pathogenesis and therapy of Landry-Guillain-Barre-tstrohl syndrome are discussed.
