新生児髄芽腫の1例

A Case of Neonatal Medulloblastoma

I．はじめに

　新生児脳腫瘍は小児脳腫瘍の約1.0％前後^15,16）と稀であり，なかでも新生児髄芽腫は現在までに20数例が報告されているにすぎない．これら新生児脳腫瘍の治療結果は未だに悲観的であるが，問題点としては，手術療法が困難であることや放射線療法の副作用等があり，今後解決されねばならない点が多い．最近われわれは新生児髄芽腫に手術，放射線および化学療法を施行した1例を経験したので，治療に関する若干の文献的考察とともに報告する．

A nine-day-old female with cerebellar medulloblasto-ma treated by surgical and radiation therapy is re-ported.

She suffered from vomiting within a few days after birth. Subsequently, her head became enlarged and she was admitted to our hospital.

CT scan on admission showed a large mass lesion at the cerebellum expanding to the pineal portion, and marked hydrocephalus.

At the age of 19 days, a ventriculo-peritoneal shunt was carried out, and at the age of 67 days, radical re-section of the tumor was performed.

The histopathological diagnosis was medulloblas-toma.
