 There is normal lumbar lordosis. The spine alignment is anatomic. The vertebral bodies, marrow and end plates demonstrate a normal MR appearance. The signal of the visualized cord is normal. The epidural space, thecal sac, and spinal cord are preserved. The conus medullaris is normal at the L1 level. The paraspinal soft tissues are unremarkable.Degenerative changes are specified by the intervertebral level as follows: At T12-L1: No evidence of disc herniation. The neural foramina and spinal canal are patent. At L1-L2: No evidence of neural foraminal narrowing or spinal stenosis. Normal disc is visualized.At L2-L3: Disc desiccation is seen. No evidence of herniation. The neural foramina appears normal with no evidence of stenosis.At L3-L4: No evidence of herniation. No evidence of neural foramina narrowing or spinal stenosis. There is moderate facet hypertrophy. There are no changes since the previous study.At L4-L5: Disc desiccation is seen. Minimal disc bulge. There is a minimal effacement of the anterior thecal sac. There is a bilateral mild neural foramina narrowing that is unchanged since the previous study. There is minimal spinal stenosis. There is facet hypertrophy that is worse than in the previous study. Hypertrophy of the ligamentum flavum is seen. The synovial cyst that was seen in the previous study along the left facet joint is not visualized and probably regressed.At L5-S1: There is minimal disc bulge with no evidence of neural foramina narrowing or spinal stenosis. There is facet hypertrophy. No changes since the previous study.
1. There is progression of facet hypertrophy at the level of L4-L5.2. No evidence of high-grade spinal stenosis or neural foraminal narrowing.3. The synovial cyst that was seen in the previous study in the left neural foramina of L4-L5 is no longer visualized, probably regressed.
