頻回の腰椎穿刺が原因と考えられる脊髄epidermoidの1例

A case of spinal epidermoid caused by lumbar punctures

I．はじめに

　今回われわれは乳児期に繰り返し施行された腰椎穿刺が原因と考えられる脊髄epidermoidの1例を経験したので若干の文献的考察を加え報告する．

A case of spinal epidermoid caused by lumbar punc-tures is reported.

The 50-year-old man, who had been diagnosed as having poliomyelitis and who had been treated with lumbar puncture 24 times when he was 1 year old, came to our clinic complaining of gradual worsening of atrophy and weakness in his right leg during the last 10 years.

Neuroradiologically, intraspinal tumor with calcifica-tion was detected in the lumbar region and partial re-moval of the tumor was performed. Pathological dia-gnosis was that it was epidermoid.

During frequent lumbar puncture at the age of 1, some small skin grafts had been implanted intrathecally and we concluded that, changing its original nature, it had grown slowly to become epidermoid.

We want to emphasize especially here that, when we performe lumbar puncture, we should, as far as possi-ble, use a small needle with stilette so as not to induce future spinal epidermoid.
