Concurrent intracranial and spinal cord arteriovenous malformations. Case report.

The authors report the case of a patient with subarachnoid hemorrhage in whom an intracranial dural arteriovenous malformation coexisted with a spinal arteriovenous malformation. The latter was considered to be the source of the hemorrhage by clinical and radiographic criteria. It is concluded that patients with subarachnoid hemorrhage who show no suitable intracranial source for their bleed in some instances should be investigated for a spinal origin of hemorrhage.
