頭蓋内圧亢進，うっ血乳頭を伴う脊髄腫瘍

Intraspinal Tumor Associated with Increased Intracranial Pressure and Papilledema

Ⅰ．はじめに

　頭蓋内圧亢進とうっ血乳頭の存在は普通頭蓋内の病変を意味するが，稀に脊髄腫瘍或いは脊髄の血管奇形がこれ等の症候を伴ってくることがある．我々は馬尾に生じたneurinomaの患者でこの現象を認め，腫瘍摘出後4年半経過を観察し，頭蓋内腫瘍が共存する可能性を否定出来たので，本症例を報告すると共にこれまでの記載例を検討し，このような現象の発生機転について考察を加えたい．

The occurrence of increased intraspinal pressure and papilledema associated with intraspinal tumor is rare. Incidence of such cases is 5.5% of the cervical and 1 to 3% of the lower intraspinal tumors.

The present authors reported a case of a neurinoma of the cauda equina causing such symptoms. A 43-year-old man was admitted to our department in December 1968 with complaints of attacks of loss of vision, headache and tinnitus. On examination, there was papilledema of 2 diopters in the both eyes. Auditory acuity was slightly diminished on the both sides.
