椎骨動脈閉塞を伴った頸部硬膜外神経鞘腫の1例

A Case of Cervical Extradural Neurinoma with Vertebral Artery Occlusion

Ⅰ．はじめに

　頸部神経鞘腫は脊髄腫瘍において決して稀なものではないが，椎骨動脈の閉塞を伴った症例の報告はきわめて少ない．今回，われわれは長期間の経過をもった巨大な頸部硬膜外神経鞘腫を経験したので，レ線上の所見とあわせて報告する．

A case of cervical extradural neurinoma with total occlusion of the right vertebral artery is reported. The patient was a 22-year-old man who had suffered slowly progressive tetraparesis for 8 years. Neurological examination demonstrated spastic tetraparesis, muscle atrophy of the trunk and four extremities, and hypalgesia corresponding to C 2, 3 and 4 dermatomes. Plain radiogram of the cervical spine revealed a large bony defect on the right side of C 2 and C 3 vertebrae and enlargement of the intervertebral foramen of the right C 2-3.
