Meningitis as a complication of Sjögren's syndrome.

Sjögren's syndrome can be complicated by several neurological manifestations, including aseptic meningitis, which can be manifested with headache, flu-like symptoms, confusion, fever, signs of meningeal irritation, with or without focal neurological symptoms and cranial nerve palsy. Neuroimaging can reveal contrast enhancement in the lepto- or pachymeninges. Therefore, Sjögren's syndrome should be considered in the differential diagnosis of lepto- or pachymeningeal enhancement.
