Aseptic Meningitis in Kikuchi's Disease

The involvement of the nervous system in Kikuchi's disease (KD) is rare. Although some reports of meningeal involvement in KD were described in the literature from Japan, it has rarely been reported in Korea. A 23-year-old man presented with severe headache, fever, and vomiting. Cerebrospinal fluid (CSF) analysis revealed an opening pressure 300 mmH(2)O, WBC 283/mm(3), glucose 44 mg/dl and protein 86 mg/dl. Multiple tender lymph nodes on the left anterior neck were found on the 9(th) day of his hospital stay. The lymph node biopsy disclosed histopathologic features typical of KD. We report a patient with KD accompanied by aseptic meningitis, emphasizing the importance of recognizing this disorder in diagnosing patients with meningitis.
