 There is trace degenerative anterolisthesis of L3 with respect to L4 and trace degenerative anterolisthesis of L4 with respect to L5. Lumbar spine alignment is otherwise within normal limits. Vertebral body and heights are preserved. A few scattered foci of increased T1 and T2 signal within the bone marrow are compatible with benign hemangiomas or focal fat deposition. Mild type II degenerative endplate changes are present at L4-L5 and L5-S1. No suspicious bone marrow replacing lesions are identified. There is moderate loss of disc height at L4-L5 and mild loss of disc height at L2-L3, L3-L4, and L5-S1. The lumbar discs are desiccated. The visualized spinal cord displays normal signal and morphology. The tip of the conus is at L1-L2. The paravertebral soft tissues are unremarkable.At T11-T12 as seen only on the sagittal images, there is a disc bulge with possible extruded component without apparent significant stenosis.L1-L2: Mild disc bulge without significant central canal or foraminal stenosis.L2-L3: Mild disc bulge and facet hypertrophy without significant central canal or foraminal stenosis.L3-L4: Mild disc bulge with superimposed central disc extrusion. The extruded component extends approximately 6 mm above the disc space and appears to remain in continuity with the disc. Mild facet hypertrophy. Mild central canal stenosis. Mild left and minimal right foraminal stenosis.L4-L5: Mild disc bulge and advanced facet arthropathy. Mild central canal stenosis. Mild left foraminal stenosis.L5-S1: Mild disc bulge and advanced facet arthropathy. No significant central canal stenosis. Moderate left greater than right bilateral foraminal stenosis.
Multilevel degenerative changes of the lumbar spine as described above. Mild central canal stenosis at L3-L4 and L4-L5. No high-grade central canal stenosis at any level. Up to moderate foraminal narrowing most prominent at L5-S1. Advanced facet arthropathy at L4-L5 and L5-S1.
