Primary cerebral neuroblastomaの1例

Primary Cerebral Neuroblastoma:Case report

I．はじめに

　副腎髄質，後腹膜および縦隔などの交感神経系細胞の分布する領域に発生するneuroblastomaは，代表的な小児悪性腫瘍の1つであるが，脳原発のいわゆるprimary cerebral neuroblastoinaは稀なものとされる．事実1978年，わが国の脳腫瘍全国集計調査報告^22）によると，原発性脳腫瘍6,204例中primary cerebral neuroblastomaはわずか9例（0.1％）にすぎない．

　われわれは最近primary cerebral neuroblastomaの1手術例を経験したので，若干の文献的考察を加えて報告する．

Primary cerebral neuroblastoma is rare.

The case reported here was a 2-year-old girl who was comatose on admission to the Mito National Hospital. She had experienced headache and vomiting during the last two months.

Neurological examination showed bilateral papilledema, left oculomotor palsy and bilateral Babinski's sign. A-P view of the left carotid angiogram showed square shift of the anterior cerebral artery to the right, and the lateral view showed upward and anterior displacement of the middle cerebral artery. CT revealed large mass lesion in the left parieto-temporal lobe, which was slightly enhanced on the contrast study.
