中脳四丘体出血の1例

Hemorrhage in the Quadrigeminal Plate: A case report

I．はじめに

　脳幹部出血のほとんどは橋出血であり，中脳原発の出血は少なく，現在までに詳しい記載のある原発性中脳出血の報告はいまだ13例を数えるのみである．しかもこのなかで，中脳四丘体に出血したという報告例はわずか1例にすぎない．

　今回われわれは中脳四丘体に出血し，急性水頭症を呈したために脳室ドレナージを行い，良好な経過をとった症例を経験したので若干の文献的考察を加え報告する．

We report a survival patient with hemorrhage in the quadrigeminal plate and discuss the literature of mid-brain hemorrhage. A 13-year-old boy developed severe headache and vertigo on April 1st, 1983. On admission, he was com-atose and tetraplegic with bilateral facial palsy and tot-al ophthalmoplegia. CT scan revealed a hemorrhage in the midbrain and ambient cistern, but vertebral angiogram no abnormal vessels.

Seven hours after admission, continuous ventricular drainage was performed. Disturbance of conscious-ness, ophthalmoplegia and speech disturbance were gradually improved.
