BackgroundDuring the past 3 decades, a handful of spinal dural arteriovenous fistula cases have been reported in which the segmental artery giving rise to the fistulous connection also supplies a radiculomedullary artery that contributes to the anterior spinal artery.Case DescriptionHere, we describe the case of a 62-year-old woman who developed spinal cord and conus medullaris dysfunction over the course of a year attributable to a spinal dural arteriovenous fistula supplied by an L1 radicular artery that also contributed to the anterior spinal artery. Despite rapid deterioration in the weeks leading up to presentation, microsurgical disconnection led to a notable improvement in motor symptoms. We present the details of our case and review the literature regarding this anatomic variant.ConclusionsRecognizing this likely rare anatomical variant is critical in optimizing functional outcome.Copyright © 2016 Elsevier Inc.
