Encephalitis associated to Kikuchi-Fujimoto's disease in a young woman: A case report

Kikuchi-Fujimoto's disease or histiocytic necrotizing lymphadenitis affects predominantly young women and most of the cases have a benign and self-limited course with a complete remission within a few months. The involvement of the central nervous system is very unusual. We present the case of a young woman who developed temporal lobe encephalitis 3 months after the onset of Kikuchi-Fujimoto's disease. The patient was treated with corticosteroid and achieved a relative good outcome although there were remaining mild cognitive impairment and behavioral disturbances.
