    Axial turbo spin echo T2-weighted sequence. Smooth erosions of the laminae with aracnoid diverticulae are clearly shown. The nerve roots are thickened and abnormally located at the periphery of the dural sac...

     
    Area of Interest: unknown; Imaging Technique: MR imaging;

    Axial turbo spin echo T2-weighted sequence. Set of images at a different level from Figure 2a reveals similar findings.
