FIG 5. A, Sagittal FSE T2-weighted (5417/98) MR image shows increased central cord signal with subtle peripheral hypointensity.
B and C, Sagittal proton density–weighted (2500/20) (B) and true T2-weighted (2500/80) (C) images show decrease in cord signal intensity (arrows).
D, Axial gradient-echo (117/20) image shows increased conspicuity of peripheral hypointensity (arrows).
E, Anteroposterior view of left L1 injection shows filling of dural arteriovenous fistula (arrow indicates catheter tip).
