Sequential MR images of the lumbar spine showing the evolution of lumbar disc degeneration in a 16-year-old female patient presenting with low back pain and evidence for stress reaction in both L5 pedicles (not shown) at the time of presentation. Sequential MR images of the lumbar spine showing the evolution of lumbar disc degeneration in a 16-year-old female patient presenting with low back pain and evidence for stress reaction in both L5 pedicles (not shown) at the time of presentation. Both intervertebral discs (L4–5 and L5–S1; also shown in magnified images) around the stressed segment demonstrated the presence of annular fissures (arrows), disc herniation, and nuclear degeneration at baseline. The control disc in the lower half of the lumbar spine (L3–4) had an intact annulus and preserved nuclear signal intensity at baseline. Follow-up MR imaging 10 months later reveals stability in the appearance of the control disc, but interval loss of signal intensity, signifying progressive nuclear degeneration of both stressed discs. The annular fissure at the L4–5 level has become less conspicuous, but one at the L5–S1 level is more easily recognizable on a follow-up scan. A. Sharma et al.
