Legend Sagittal and Axial T2WIs show multiple serpiginous flow voids within the intradural extra medullary space with a heterogeneous mass in the right extradural compartment.

Legend Left: Post contrast Sagittal and Axial T1WIs with fat saturation show enhancement within the dilated vessels (likely due to slow flow), as well as near-homogeneous intense enhancement of the right-sided mass. MIP reconstructed view of a contrast MRA shows a highly vascular mass supplied predominantly by a lumbar artery and tortuous, dilated draining veins. Key words: mri mra lumbar tumor vascular neoplasia
