Gangliogliomaの1小児例

Ganglioglioma in A Child: Report of a case

I．はじめに

　中枢神経系に生ずるgangliogliomaは極めて稀な腫瘍である．最近われわれは，7歳の男子で左頭頂葉皮質下に生じたgangliogliomaの1例を経験したので，若干の文献的考察を加え報告する．

A seven-year-old boy who was admitted for surgical treatment for intractable epilepsy was found to have a ganglioglioma in his left parietal lobe. Since four years old, he had been suffering from the seizure and treated with various anticonvulsants withoutsatisfactory effects. As its frequency increased, the dose had to be increased. Thus, it was sought for the possible surgical approach.

On the CT scans, an egg size low density zone without contrast enhancement was observed in the subcortical region of his parietal lobe. There was marked thinning on inner table of the skull immedi-ately above the zone.
