 For the purposes of numbering, the inferior most fully formed intervertebral disc space is considered to be the L5-S1 disc space. There is mild straightening of the lumbar lordosis which may be positional. There is minimal retrolisthesis of L2 over L3. The vertebral body heights and intervertebral disc spaces are maintained. The no worrisome focal marrow signal is demonstrated. The distal spinal cord and cauda equina demonstrate normal caliber and signal intensity. The conus terminates at L1-2.L1-2: No significant disc herniation, neuroforaminal stenosis or spinal canal stenosis is noted at this level.L2-3: There is a mild diffuse disc bulge with suggestion of an annular fissure and small left extraforaminal protrusion contacting the left L2 nerve root. There is mild facet arthropathy and tiny small synovial cyst posterior to the right facet joint better seen on sagittal STIR sequence.L3-4: No significant disc herniation, neuroforaminal stenosis, or spinal canal stenosis is noted at this level.L4-5: There is a mild diffuse disc bulge with central/right paracentral protrusion without significant central spinal canal or neural foraminal stenosis at this level.L5-S1: There is a minimal diffuse disc bulge without significant neuroforaminal or spinal canal stenosis at this level. Mild hypertrophic degenerative changes of the posterior facets are demonstrated.
Mild degenerative changes of the lumbar spine, relatively worse at L2-3 where there is a mild diffuse disc bulge and suggestion of a small left extraforaminal protrusion which may be contacting the left L2 nerve root. There is no significant spinal canal stenosis at any level. There is also no high-grade neural foraminal stenosis at any level.
