Abstract
Sjogrens syndrome (SS) is an autoimmune disorder characterized by lymphocytic and plasma cell infiltration of exocrine glands, resulting in dry mouth and keratoconjunctivitis sicca. The clinical symptoms may range from mucosal dryness to more systemic complaints. We report a 42-year-old man presenting with rapid cognitive decline and memory impairment for 2 months. Magnetic resonance imaging of the cranium revealed abnormal signals at the bilateral medial temporal lobe and hippocampal region. The autoimmune panel and paraneoplastic antibodies were negative. The patient was labeled as a case of primary SS based on the vasculitis profile and pathological examination of lip biopsy. This case illustrates a rare, heralding manifestation of SS as limbic encephalitis.
