Large lumbar disc prolapse


Large L5/S1 disc prolapse with right S1 nerve root impingement.

A striking example of disc prolapse. You can literally feel the pain from the compression on the descending S1 nerve root.

A good candidate for surgical treatment.

A couple of practical points from this case.

  1. when you can see the disc prolapse on the localizer its likely to be a biggy
  2. compare and contrast the axial T2 and T1 images.  Although many protocols only do an axial T2, in cases like this the axial T1 for me really shows the nerve root compression in a more impressive format
