Perimedullary Spinal Arteriovenous Malformation in an Elderly Female: A
Perimedullary spinal AVM is a rare type of spinal arteriovenous
malformations. We present a case of 70 yrs female who presented with
motor weakness in her bilateral limbs. Initial MRI was misinterpreted as
ependymal myxoma; however, histopathology revealed spinal AVM. MRA or
DSA should be conducted if AVM is suspected.
