FIG 1. A, Anteroposterior view of spinal angiogram (injection of intercostal artery) shows filling of an SDAVF with pial drainage (arrowheads; arrow indicates catheter tip).
B, Sagittal contrast-enhanced T1-weighted (500/11) MR image shows enhancing enlarged pial vessels as well as intrinsic cord enhancement.
C, Axial FSE T2-weighted (4500/90) image shows peripheral hypointensity (closed arrow) with increased central cord signal (open arrows).
D, Sagittal FSE T2-weighted (2700/85eff) image shows enlarged pial vessels, central increased signal, and peripheral hypointense rim (arrows).
