Dural arteriovenous fistulas of the craniocervical junction

Dural arteriovenous fistulas (DAVF) involving the craniocervical junction a re uncommon lesions that may result in neurological deficits referable to p osterior fossa structures and/or the spinal cord. We report on two patients with cranio cervical junction DAVF whose venous drainage involved the cerv ical spinal cord. Both cases presented with progressive quadriparesis and p arenchymal magnetic resonance signal abnormality of the cervical spinal cor d. Both patients improved following embolization of the fistulas. AVF of th e craniocervical junction are an uncommon, but important cause of treatable neurological deficits referable to this region of the nervous system.
