Fracture of the sella turcica:A case report and review of literature

I．はじめに

　脳神経外科医が頭部外傷患者を診察することは多いが，トルコ鞍に骨折を認める例に遭遇する機会は極めて稀であり，その報告例も少ない，最近われわれは，トルコ鞍骨折を伴い，脳神経麻痺，髄液鼻漏，尿崩症，さらに下垂体前葉機能低下などの多彩な病態を合併した1例を経験したので，トルコ鞍骨折の報告例22例とともに，主に骨折の機序や合併症について検討したので報告する．

The incidence of a fracture of the sella turcica is reportedto be rare and the authors reported a case of a sellar fractureassociated with several neurological and endocrinologicalcomplications.
