脊椎管内くも膜下血腫の1例

Spontaneous Spinal Subarachnoidal Hematoma:Case Report

Ⅰ．はじめに

　脊髄損傷を伴わない脊惟管内血腫は極めて稀な疾患である．これを大別するとその部位により硬膜外，硬膜下，くも膜下に分ける事が出来る．この内くも膜下血腫は調べ得た範囲においては，Bouzarch（1968）^6）の2例であった．

　最近我々の教室に於いて，脊部痛，両下肢麻痺，膀胱直腸障害を主訴とし，手術により脊椎管内くも膜下血腫と診断された1症例を経験したので報告する．

"Spontaneous intraspinal canal hematomas" are rare clinical conditions. These are classified as epidural, subdural and subarachnoid. Especially, subarachnoid hematoma is rare only two cases being reported by Bouzarth (1968).

We have reported surgical treatment of a female with intraspinal canal subarachnoid hematoma.

The patient presented with sudden onset of backpain, followed by paraplegia, sensory impairment and urinary retention. A lumbar tap revealed bloody CSF a complete block. A left vertebral angiography was narmal. However, a myelography showed a filling defect at Th5.
