Spinal cord ischemia, as represented by acute paraplegia, is rare in t
he absence of trauma. It is even more uncommon that an infarction of t
he spinal cord occurs in a patient with no predisposition to vascular
disease. We report a case of anterior spinal artery syndrome resulting
from an infarction of the anterior aspect of the spinal cord in an ot
herwise healthy 45-year-old woman.
