脳橋膠腫，多発性硬化症を思わせた特発性脳橋血腫の1例

A Case of Spontaneous Pontine Hematoma in Patient suspected of Pontine Glioma and Multiple Sclerosis

Ⅰ．はじめに

　特発性橋血腫のなかに比較的若年者にみられ，急性または亜急性に発症し，進行性の経過をたどるが症状の動揺，緩解をくり返すために脳橋膠腫，多発性硬化症と誤診される例のあることは良く知られている．われわれも同様の症例を経験したので，それらの鑑別診断について考察し，あわせてCTの有用性について報告する．

A case of spontaneous pontine hematoma in young boy, with remitting and relapsing clinical course of up to 11 years, suspected of having pontine glioma or mul-tiple sclerosis is reported. Differential diagnosis of these are mentioned with reference to our cases of pontine glioma.

This patient was a man aged 16. At 5 years of age he had his first episode of double vision. 20 days after first episode, gait disturbance, left facial palsy and cons-ciousness disturbance developed. Neurological and ne-uroradiological examination revealed a pontine glioma and radiotherapy was administered.
