新生児脳腫瘍の2例—その文献的集計

TWO CASES OF BRAIN TUMOR IN THE NEONATAL PERIOD:Consideration for the Ever Reported 7 Cases

I．はじめに

　小児神経病学および小児脳外科学の発達に伴い，小児の脳腫瘍は最近その数を増してきてはいるが，乳幼児特に1歳未満の乳児脳腫瘍となるとその数はいまだ少ない。なかでも新生児の脳腫瘍は文献上においてもきわめて稀で，その性格についてもいまだ統一的見解を出すには至つていない状態である。

　最近われわれは生下直後より神経症状を認め，諸種検査により脳腫瘍と診断し，死後剖検する機会を得，組織学的にもmedulloblastomaとglioblastoma multiformeが共存していたきわめて興味ある症例および帝王切開にて出生，そのときすでに巨大頭蓋を認め，剖検にて大脳中央深部に巨大な奇形腫を認めた計2例の新生児例を経験したので報告し，併せて生後2ヵ月以内の新生児脳腫瘍症例を文献的に収集し，考察を加える。

Brain tumor in the neonatal period is extremely rare. We have presented 2 cases of brain tumor in the neonatal period, and summed up ever reported 71 cases of brain tumor within 2 monthes.

Case I: 26 days old female infant who had com-plained left facial paralysis and dysphagia since her birth, and died on the next day of her admission. In autopsy, the tumor was located at the left cerebello-pontine angle and 20g in weight, which consisted of two elements of medulloblastoma and glioblastoma multif orme histologically.

Case II: one day old female infant, who was deli-vered by cesarean section. She had large head already at the time of the birth, and died 6 days after her admission and autopsy was performed. The tumor was situated at the deep midline portion of the brain, and teratoma in histology.
