title: Selective conformal radiotherapy for arteriovenous malformation involving the spinal cord.
abstract: Radiotherapy has seldom been used in the treatment of arteriovenous malformations (AVM) involving the spinal cord because of the cord's limited radiation tolerance. A 57-year-old woman with progressive myelopathy due to AVM was treated with a selective conformal radiation therapy (55.6 Gy/20 days) on the nidus region preserving the spinal cord, drainer veins and involved bones. The drainers and symptoms were minimized at the end of treatment and disappeared over 2 years. This case illustrates the usefulness of selective conformal radiation therapy.
