Anterior spinal artery infarction.

Spinal cord ischemia, as represented by acute paraplegia, is rare in the absence of trauma. It is even more uncommon that an infarction of the 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 otherwise healthy 45-year-old woman.
