Trochlear nerve palsy in Sjogren's syndrome

Sjogren's syndrome (SS) is a systemic lymphoproliferative, autoimmune disea se, which is characterized by dryness of the eyes, mouth, and other mucous membranes. The nervous system may be affected in up to 20% of the cases of primary or secondary SS. We present a case of a 54-year-old woman with troc hlear nerve palsy complicating Sjogren's syndrome secondary to rheumatoid a rthritis. We suggest that all patients with multiple cranial neuropathies, especially when associated with rheumatoid arthritis, should be carefully e xamined for the possible presence of secondary SS.
