A case of primary Sjögren's syndrome presenting primarily with central nervous system vasculitic involvement.

Sjögren's syndrome is primarily a chronic systemic autoimmune disease that affects exocrine organs. Neurologic symptoms frequently present as peripheral neuropathy due to small vessel vasculitis. Type and prevalence of central nervous system involvement are still controversial. In this report, we present a 35-year-old woman with primary Sjögren's syndrome with central nervous system vasculitic involvement.
