 The last well-formed disk space is referred to as L5-S1. There is normal alignment of the lumbar spine. The vertebral body heights are preserved. There is disk desiccation at multiple levels of the lumbar spine with mild loss of disk height. The osseous marrow signal is benign. The conus terminates at T12-L1 and shows normal caliber and signal characteristics.T12-L1: Mild disk bulge without significant central spinal canal or neural foraminal stenosis.L1-2: No disk herniation, central spinal canal or neural foraminal stenosis.L2-3: Diffuse disk bulge with right paracentral/foraminal protrusion, and mild facet arthropathy causing minimal right neural foraminal stenosis and no significant central spinal canal stenosis. Disk material encroaches upon the right subarticular zone without significant stenosis.L3-4: Mild diffuse disk bulge and mild facet arthropathy causing no significant spinal canal or neural foraminal stenosis.L4-5: Diffuse disk bulge asymmetric to the right with right foraminal protrusion and annular fissure, mild bilateral facet arthropathy causing mild right neural foraminal stenosis. Disk material encroaches upon the bilateral subarticular zones without stenosis. No significant spinal canal or left neural foramina stenosis.L5-S1: Diffuse disk bulge asymmetric to the left and mild bilateral facet arthropathy causing minimal left neural foraminal stenosis. No significant spinal canal or right neural foraminal stenosis.There are bilateral small renal cysts.
Mild multilevel lumbar degenerative changes with no significant spinal canal stenosis and minimal neural foraminal narrowing as detailed above. I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
