Preserved Lumbar Curve With Good Vertebral Alignment  Normal Dimensions

Preserved lumbar curve with good vertebral alignment
 Normal dimensions of the bony lumbar spinal canal.
 Relative diffuse homogenous low marrow signal likley related to
red marrow hyperplasia.
 Otherwise, no vertebral structural collapse or marrow signal
alteration.
 Reduced normal bright T2 signal of L4/5 with preserved height
denoting reduced hydration.
 L4/5 posterior annular disc relaxation with no significant spinal
or neural compromise.
 Otherwise, no MR evidence of lumbar discs herniation or bulge.
 Normal MR signal of the conus medullaris & cauda roots.
 No gross facetal arthropathy.
 No paravertebral masses or collections
OPINION:
 L4/5 posterior annular disc relaxation.
