微小血管減圧術後にアレルギー反応に起因した無菌性髄膜炎を合併した2例

Aseptic Meningitis as a Complication Caused by an Allergic Reaction after Microvascular Decompression:Two Case Reports

Ⅰ．はじめに

　われわれは微小血管減圧術（microvascular de-compression：MVD）後に無菌性髄膜炎を合併した2症例を経験した．両者とも類似した臨床経過をとり，その病態を検討したところアレルギー反応に起因する髄膜炎が考えられたので，若干の文献的考察を加え報告する．

We report here two cases of patients complicated with aseptic meningitis after microvascular decompression (MVD). The first case, a 56-year-old female complained of headache with high fever 18 days after the MVD for right trigeminal neuralgia. The amount of cells in cerebrospinal fluid (CSF) had so much increased that bacterial meningi-tis was suspected. However, there was no improvement after antibiotics therapy, so immune globulin was injected and the meningitis gradually improved. Eosinophilia remained in peripheral blood and the symptoms improved rap-idly after the steroid therapy.
