Deep sylvian meningiomaの1例

A Case of Deep Sylvian Meningioma

Ⅰ．緒言

　meningiomaはその発生原基がarachnoid remnantにあるとされ，実地臨床上経験される症例のほとんどはdura materあるいはchoroid plexusにattachmentを存しており，いわゆる脳表面に全く現れないで脳実質内へ発育していくものはきわめて稀である．

　我々は最近臨床的にdeep sylvian meningiomaと診断された1例を経験したので報告する．

So called intracerebral or subcortical meningioma with no relation to the ventricles is extremely rare. In 1938 Cushing and Eisenhardt reported two cases of this type of tumor as "Deep Sylvian Meningiomas" The authors reported a case of "deep sylvian men ingioma" because of its rarity and interesting diagnostical questions, and 16 cases reported in the literature were reviewed.
