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.
Abstract
The association of two aneurysms on the distal posteroinferior cerebellar artery with an arteriovenous malformation fed by the same artery is reported. A one-stage operation was performed. The other cases in the literature are analyzed with particular regard to the origin of the subarachnoid hemorrhage and the location of the aneurysms.
