 The lumbar spine is in normal alignment, with a normal lumbar lordosis. The vertebral body heights are well-maintained. There is minimal loss of intervertebral disc space height at L4-5. Intervertebral disc space heights are otherwise well-maintained. There is disc desiccation at the L1-2 and L4-5 levels. Multilevel Schmorl nodes are noted. Heterogeneous bone marrow without evidence of marrow edema. The distal spinal cord and conus are within normal limits with the conus terminating at the L1-2 intervertebral level.L1-2: New tiny central annular fissure is noted. No significant spinal canal or neural foraminal stenosis.L2-3: Minimal left foraminal shallow disc protrusion. No significant spinal canal or neural foraminal stenosis.L3-4: Mild disc bulge with biforaminal prominence. Mild facet joint hypertrophy. Mild bilateral neural foraminal stenosis, left greater than right. No significant spinal canal stenosis.L4-5: Mild disc bulge. Mild-to-moderate facet joint hypertrophy and ligamentum flavum thickening. Mild bilateral neural foraminal stenosis. No significant spinal canal stenosis.L5-S1: Mild facet joint hypertrophy. No significant spinal canal or neural foraminal stenosis.
1. Mild disc bulge at the L3-4 and L4-5 levels, with mild bilateral neural foraminal stenoses, without significant interval change. 2. New tiny central annular fissure at the L1-2 level. 3. Other mild degenerative changes of the lumbar spine as described above.
