前頭蓋窩硬膜動静脈奇形の1例

A Case of Dural Arteriovenous Malformation in the Anterior Fossa

I．はじめに

　硬膜動静脈奇形は稀な疾患とはいえないが，その大部分は横・S状静脈洞部および海綿静脈洞部に存在し，前頭蓋窩硬膜動静脈奇形の報告は非常に稀である．今回，われわれは前頭蓋窩硬膜動静脈奇形の1例を経験したので，文献例16例とともに若干の文献的考察を加えて報告したい．

Dural arteriovenous malformations (AVMs) are not uncommon. But most of dural AVMs are located in the cavernous portion or the transverse-sigmoid portion. Dural AVMs in the anterior fossa and very rare. We experienced a case of dural AVM in the anterior fossa and review 17 cases of dural AVM in the anterior fossa in the literature.

Case : a 62-year-old male was admitted to our center because of unconsciousness and vomiting on Sept. 28, 1985. For nineteen months he had been on anticoagu-lant therapy after aorto-coronary bypass. Neurological examination on admittion revealed somnolence and right-hemiparesis.
