Sjogren’s Syndrome (SS) is a chronic autoimmune disorder that may be complicated by neurological dysfunctions. The involvement of cranial nerves in SS was described as a very rare complication. Moreover, bilateral peripheral facial paralysis associated with SS has been described only in 3 patients in the literature and the first case was described by Henrik Sjogren himself in 1935. We report a 59-year-old female with bilateral peripheral facial paralysis associated with Sjogren’s syndrome. She was treated with 5-day IVIG consecutively and continued oral methylprednisolone 16mg/day and almost fully recovered at 2 months of follow-up examination. Acute bilateral peripheral facial palsy in SS is a very rare condition and Lyme disease, Guillain-Barré syndrome, HIV infection, and central nervous system lymphoma should be considered in the differential diagnosis. As a result, SS should be considered as an underlying cause of bilateral facial paralysis.
