脊髄多発性神経鞘腫の1例

Multiple Neurinoma of the Spinal Cord: Case report

I．はじめに

　脊髄神経鞘腫は脊髄腫瘍の中で最も多いものである．しかしながら多発性で，しかも各々解剖学的部位を異にする症例の報告は極めて稀である．今回われわれは中位胸髄から腰髄にかけ髄内から髄外，硬膜内髄外，硬膜内外と独立して存在した神経鞘腫の1例を経験したので，文献的考察を加えて報告する．

The patient, a 72-year-old female, was admitted with an 11-year history of progressive dysesthesia in the left leg. Neurological findings on admission revealed weak-ness in the bilateral legs, hyperreflexia of left leg, hypalgesia and hypesthesia under the Th 8 level, and urinary incontinence.

Plain lumber X-ray showed enlargement of the inter-vertebral foramen of L 1/2. Myelography disclosed block age at the level of Th 9 and filling defect at the level of Th 10/11 and L1/2.
