[Recurrent facial palsy, primary Gougerot-Sjögren's syndrome and vitamin B12 deficiency]

Abstract

Introduction: Differing cranial nerve involvement has been reported in the context of Gougerot-Sjögren's syndrome. Involvement of the V, III and VII nerves has been reported, the most characteristic being nerve V, notably its lower branch. Rare, well documented, cases of facial palsy have also been described.

Observation: Recurrent facial palsy in a 40 year-old woman revealed a primary Sjögren's syndrome and vitamin B12 deficiency.

Discussion: The onset of facial palsy has been linked with Gougerot-Sjögren's syndrome. The contribution of vitamin B12 deficiency is discussed.
