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