髄内発育を示した頸髄神経線維腫の1例

Intramedullary Neurofibroma in the Cervical Spinal Cord;A case report

I．はじめに

　脊髄の神経鞘腫・神経線維腫は発生頻度の高い腫瘍であるが，脊髄神経線維腫が髄内に発育することは極めて稀である．われわれは，頸髄髄内に発育した神経線維腫の1例を経験したので，その発生機序，画像診断について文献的考察を加え報告する．

Abstract

A 62-year-old woman was admitted complaining of clumsiness in both hands. On neurological examination, bilateral hand muscles were weak, both legs were spas-tic and hyperreflexic, all the extremities were hypoes-thetic.

Urological examination revealed detruser sphincter dyssynergia. Spinal CT scan demonstrated an iso densi-ty mass lesion in the cervical spinal cord, and it was markedly enhanced. On MRI, it was also markedly en-hanced by Gd-DTPA.
