 The vertebral body heights are preserved. Mild L3-4 anterolisthesis. Alignment is otherwise maintained. There is severe loss of disc height with endplate degenerative changes at L5-S1 with vacuum phenomenon. There are scattered T1 hyperintense foci of the lumbar spine, which may represent focal fatty replacement or fat containing hemangiomas. No suspicious osseous lesions. There is no significant spinal canal stenosis. The distal spinal cord displays normal signal and morphology. The paravertebral soft tissues are unremarkable.Individual levels as below:T11-T12: Mild disc bulge. No significant spinal canal or foraminal stenosis. These findings are unchanged.T12-L1: Bilateral facet arthropathy. No significant disc bulge, spinal canal or foraminal stenosis. These findings are unchanged.L1-L2: There is a new right paracentral disc extrusion that extends above the disc level causing marked right lateral recess stenosis. As before, there is bilateral facet arthropathy and mild disc bulge, moderate right foraminal stenosis, no significant spinal canal or left foraminal stenosis, unchanged.L2-L3: Mild disc bulge and bilateral facet arthropathy. Mild bilateral foraminal stenosis. No significant spinal canal foraminal stenosis. These findings are unchanged.L3-L4: Mild disc bulge with superimposed right foraminal protrusion and advanced bilateral facet arthropathy, contributing to mild right foraminal stenosis. There are also bilateral facet effusions. No significant spinal canal or left foraminal stenosis. These findings are unchanged.L4-L5: There is mild neural foraminal narrowing on the right related to advanced facet arthropathy. Otherwise no significant spinal canal or neural foraminal stenosis. These findings are unchanged.L5-S1: Disc bulge and bilateral facet arthropathy, contributing to moderate left foraminal stenosis with flattening of the left S1 nerve root sheath origin. No significant spinal canal stenosis. These findings are unchanged.SI joint: There are minimal marginal osteophytes.
