Meningiomaと眼症状

Ocular Signs in Meningioma

I．緒言

　脳腫瘍の診断に眼科的検査を欠くことの出来ないことは万人の知るところである。古来幾多の報告がなされているがわれわれは最近24例のme—ningiomaを経験したので，その部位と眼症状との関係を分析してみた。

　症例は次に示すごとく24例である。

Twenty-four cases of intracranial meningi-oma were analysed as to their ophthalmologi-cal features. The cases consisted of 10 fema-les and 14 males.

The interval between the occurrence of ini-tial subjective symptoms and the seeking of medical advice lay within one year in 63% of the cases. Half of the patients were less than 40 years of age.

The tumor was located over the sphenoidal ridge in 6 cases, in parasagittal lobe in 4 ca-ses, in subfrontal lobe in 3 cases and in cere-bral lobe in 11 cases.

In cases with sphenoidal ridge meningioma papilloedema, Foster-Kennedy's syndrome and hemianopsia homonyma occurred in 33% each.
