 The last well-formed disk space is referred to as L5-S1, similar to last exam. There is stable mild grade 1 retrolisthesis of L2 on L3, minimal retrolisthesis of L3 on L4, and minimal anterolisthesis of L4 on L5. There is disk desiccation at all levels in the lumbar spine with up to moderate loss of disk height and L1-2, similar to prior exam. There is focal superior endplate chronic Schmorl's nodes at L2, L4 and L5 stable from prior exams. There is mild loss of vertebral body heights at L2 and L5 which is also unchanged and without evidence of bone marrow edema. The osseous marrow signal is heterogeneous but benign, with areas of fatty deposition. The conus terminates at L1-2.L1-2: Stable diffuse disk bulge with central protrusion, bilateral facet arthropathy, and new left foraminal annular fissure. No significant spinal canal or neural foraminal stenosis.L2-3: Stable moderate diffuse disk bulge, bilateral facet arthropathy and ligamentum flavum thickening causing mild encroachment upon the bilateral L3 nerve roots in the subarticular zones. No significant central canal or neural foraminal stenosis.L3-4: Diffuse disk bulge, facet arthropathy, and ligamentum flavum thickening causing mild to moderate spinal canal stenosis and moderate right and mild left neural foraminal stenosis similar to prior exam.L4-5: Diffuse disk bulge with right foraminal/far lateral protrusion, facet arthropathy and ligament flava thickening with mild right neural foraminal and mild spinal canal stenosis and no signfiicant left neural foraminal stenosis.L5-S1: Diffuse disk bulge, bilateral facet arthropathy, and ligamenta flava thickening causing mild bilateral neural foraminal stenosis and no significant spinal canal stenosis.
1. No significant interval change in multilevel lumbar spondylosis as described above. No high grade spinal canal stenosis at any level. There is up to moderate right L3-4 neural foraminal stenosis.2. No findings to suggest metastatic disease.
