She had a sudden onset of abdominal pain and bladder disturbance about 3 years ago, and had gait disturbance due to weakness of bilateral limbs 9 days later, 3 months later she recovered gradually and ambulated with a stick. Eight months later, she had the 2nd attack and since then she could never walk again. The angiography showed 2 midus of glomus type of angiomas in the 9th thoracic lesion.
