Subacute aseptic meningitis as neurological manifestation of primary Sjögren's syndrome.
Sjögren's syndrome (SS) is an autoimmune disease characterized by inflammatory infiltration and secondary chronic dysfunction of exocrine glands. Systemic (extraglandular) manifestations of the disease occur in one-third of the patients, including a wide spectrum of peripheral and central neurological disorders. We report a case of subacute afebrile aseptic meningitis (AM) as neurological manifestation of primary SS. The neurological symptomatology presented gradual onset and progression, including diplopia, mild headache, pain and stiffness of the neck. The clinical examination pointed out xerostomia and xerophthalmia. Diagnosis of SS was confirmed by Schirmer's tear test and histopathology of the labial salivary glands. The neurological involvement was highlighted by gadolinium-enhanced magnetic resonance imaging of the brain which displayed an increased diffuse leptomeningeal enhancement. Cerebrospinal fluid (CSF) analysis showed moderate pleocytosis with prevalence of polymorphonuclear leukocytes and increased protein level but no evidence of Ig intrathecal synthesis. A cycle of intravenous steroid therapy led to a complete disappearance of the neurological symptomatology and to normalization of the CSF inflammatory pattern. Given the unusual presentation of this case of AM, which resembled the characteristics of a chronic meningitis rather than those of an acute form, in patients affected by SS we must stress the importance of cephalic symptoms such as headaches and cervical stiffness (even if mild and without fever) as possible signs of central neurological involvement of the disease.
