Campylobacter fetusによるinfected subdural hematomaの1例

A Case of Infected Subdural Hematoma due to Campyrobacter Fetus

I．はじめに

　慢性硬膜下血腫に血行性に感染が波及し生じるinfected subdural hematomaは，いわゆる硬膜下膿瘍とは発生機序や病態が異なりきわめて稀とされている．われわれが猟渉できた範囲では本例を含めて18例の報告があるのみである．今回，健康な若年成人で，生レバーからCampylobacterfetusに感染しinfected subdural hematomaを来した1例を経験した．MRIがinfected subduralhematomaの診断と経過観察に有用であったため文献的考察を含め報告する．

A 20-year-old male presented fever, nausea and headache 1 week after eating uncooked liver. On admis-sion, it was revealed he had sufferd a closed head injury 3 months before without unconsciousness. Onadmission, computed tomography scan showed a left chronic subdural hematoma. Gd-DTPA magnetic re-sonance images revealed unusual enhancement of the capsule and linear enhancement of the subarachnoidspace.

The patient underwent burr hole irrigation and drainage. The culture of the hematoma content showedCampylobacter fetus. Therefore, the diagnose was infected subdural hematoma. A drainage operation andadministration of antibiotcis were effective.

Our case suggests that enhanced magnetic resonance images are useful for diagnosis and follow-up of in-fected subdural hematoma.
