Left leg pain Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. Alignment of the lumbar spine is grossly maintained aside from mild straightening and trace retrolisthesis at L2-L3, L3-L4, L4-L5, and L5-S1. There is mild progression of degenerative disease with a T1 hypointense and T2/STIR hyperintense lesion involving the superior endplate, which is favored to represent an acute Schmorl's node and new since prior. Small Schmorl's node involving the superior L3 endplate also noted which is new but without significant edema. Endplate changes/Schmorl's nodes involving L3-L4 endplates are unchanged. Disc space narrowing at multiple levels is again seen, worst at L5-S1. The conus medullaris is normal in position.Individual levels as described below:L1-L2: Minimal disc bulge. No significant spinal canal or neural foraminal stenosis.L2-L3: Disc bulge without significant spinal canal or neural foraminal stenosis. L3-L4: Diffuse disc bulge without significant spinal canal stenosis. There is mild bilateral neural foraminal stenosis. L4-L5: Diffuse disc bulge with a left foraminal protrusion component which effaces the left lateral recess and results in moderate to severe left foraminal stenosis, minimally worse since prior study from 11/9/2012. Moderate central canal stenosis appears similar. There is minimal right neural foraminal narrowing. Bilateral facet arthropathy.L5-S1: Minimal disc bulge and endplate osteophytes without significant spinal canal stenosis. There is mild to moderate and minimal right left and mild right neural foraminal stenosis similar to prior. Mild left facet arthropathy.Paraspinous soft tissues are within normal limits.
Mild progression of multilevel degenerative changes compared to 11/9/2012. There is a disc protrusion at the left L4-L5 level involving the left lateral recess and left neural foramen. There may be impingement of the exiting left L4 and descending left L5 nerve roots at this level. There is also mild to moderate left L5-S1 neural foraminal stenosis which is similar to prior. Please see details above.
