Ependymal cystの1例

Ependymal Cyst: Case report

I．はじめに

　頭蓋内には発生起源，組織学的特徴から見てさまざまな嚢胞が発生するが，脳内またはくも膜下腔に発生するependymal cystの報告は多くない．われわれは左右大脳半球にまたがる巨大なependymal cystの1例を経験したので，若干の文献的考察を加えて報告する．

An eleven-month-old male infant with an epen-dymal cyst is reported. He was born after full-term pregnancy and vacuum extraction. His growth and development was somewhat retarded and he could control his head at the age of five months. He was admitted to our hospital because of the enlargement of his head and the paretic right upper limb. On admission he was found to be a well-nourished infant with the head circumference of 54.5 cm and the height of 75.5 cm. Physical examination disclosed slight weakness in the right upper extremity but no signs of increased intracranial pressure.
