Female, 44 years old, with low back pain for one month. Spinal alignment is anatomic. Vertebral body height and morphology are within normal limits. No evidence of edema or marrow replacement is seen. The visualized distal spinal cord, conus and nerve roots of the cauda equina are unremarkable. No epidural abnormalities are suspected.At L1-2 and L2-3, no significant abnormalities are detected.At L3-4, mild facet arthropathy is seen without significant spinal canal or foraminal stenosis.At L3-4, mild arthropathy is seen without significant spinal canal or foraminal stenosis.At L4-5, advanced facet degeneration is seen along with ligamentum flavum thickening. Disc is bulging with a small superimposed right paracentral/foraminal protrusion. The right lateral recess is effaced and there is a moderate generalized spinal canal stenosis with moderate right and mild left foraminal narrowing.At L5-S1, advanced facet arthropathy is seen, left greater than right. No significant spinal canal stenosis is demonstrated, but the neural foramina are mildly narrowed.
1.Disc and posterior element degeneration at L4-5 result in a moderate generalized spinal canal stenosis and moderate narrowing of the right neural foramen. 2.Relatively mild degenerative changes are seen at additional levels without significant compromise of the spinal canal or neural foramina.
