length, and enhancement: systematic approach to differentiating intramedullary spinal cord lesions. Dural arteriovenous fistula. A 50-year-old male with gradual onset of inability to walk, off and on constipation, and urinary incontinence. a Axial T2 image demonstrates hyperintensity in the cord and multiple serpiginous flow voids (arrow) within the thecal sac. b Sagittal T2 image reveals long segment involvement (bracket). c Conventional spinal angiogram shows injection of a paraspinal artery with simultaneous robust filling of a corkscrew venous vessel

Location,

length, and enhancement: systematic approach to differentiating intramedullary spinal cord lesions. Dural arteriovenous fistula. A 72-year-old male with progressive lower extremity weakness, without improvement in symptoms after lumbar laminectomy. a Axial T2 image demonstrates numerous flow voids in the thecal sac (arrowhead). There is high signal in the cord due to congestion (arrow). b There is long-segment high T2 signal in the cord, with serpiginous vessels in the posterior thecal sac (bracket). c Spinal angiogram shows the right T4–T5 supreme intercostal artery as a feeding vessel. d MRA confirms the arteriovenous connection
