転移性脊髄髄内腫瘍の2症例

Intramedullary Spinal Cord Metastasis:Two Case Reports and Literature Review

Ⅰ．はじめに

　悪性腫瘍の脊椎や脊髄硬膜外・硬膜下腔への転移は比較的よくみられるが，脊髄髄内への転移は稀とされている．しかし，近年の画像診断の進歩や悪性腫瘍に対する治療技術の向上に伴い転移性脊髄髄内腫瘍を経験する機会が増すことが予想される．今回われわれは，悪性腫瘍の脊髄髄内転移を来した2症例を経験したので報告する．

Intramedullary spinal cord metastasis was thought to be rare, but the advent of MR imaging and treatment for ma-lignancy have revealed that it is more frequent than we previously thought. We report two cases of intramedullary spinal cord metastasis from lung and rectal colon carcinoma. Their symptoms were aggravated rapidly. We performed surgical treatment in both cases;one was grosstotal and the other was subtotal resection. After the operation, symp-toms improved mildly in one patient and worsened in the other patient.
