BackgroundSpinal dural arteriovenous fistulas (SDAVFs) are the most common type of spinal arteriovenous malformations; they frequently cause progressive myelopathy including gait disturbances and sensory disorders.Case DescriptionWe report a rare case of a middle-aged man who experienced right-sided chest pain and Th4 radiculopathy, without any other neurologic presentations. Magnetic resonance imaging showed a flow void sign on the dorsal aspect of the spinal cord; spinal angiography revealed an arteriovenous shunt between a radicular artery and an intradural vein. Suspecting SDAVF as the cause of the chest pain, we performed surgical resection. Intraoperatively, we observed compression of the rootlet by the draining vein. Right chest pain disappeared completely after obliteration of the SDAVF. The present patient had vascular compression of the spinal nerve rootlet without any venous congestion.ConclusionsOur experience shows that SDAVF can present not only as a myelopathy but also as a radiculopathy, indicating that radiculopathy may become a main symptom of SDAVF.Copyright © 2020 Elsevier Inc.
