 Alignment of the lumbar spine is anatomic. There are 5 lumbar type vertebral bodies. The vertebral body heights are preserved. The bone marrow signal is normal. Mild degenerative spondylosis affects the lower lumbar spine L4-5 and L5-S1 where there is disc desiccation. The conus is normal in signal and morphology and terminates at L1. The visualized intra-abdominal and paraspinal contents are unremarkable.No spinal canal stenosis or neural foraminal narrowing at T11/12 or T12/L1 as seen on the sagittal images.L1/2: Mild facet arthropathy without spinal canal stenosis or neural foraminal narrowing.L2/3: Mild facet arthropathy without spinal canal stenosis or neural foraminal narrowing.L3/4: Minimal disc bulge, facet arthropathy and ligamentum flavum thickening with minimal bilateral neural foraminal narrowing. No spinal canal stenosis.L4/5: Small annular fissure. Minimal disc bulge, facet arthropathy, and ligamentum flavum thickening with minimal left and no right neural foraminal narrowing. No spinal canal stenosis.L5/S1: Small annular fissure. Disc bulge, eccentric to the right, which contacts the right L5 nerve extraforaminally without clear impingement. Mild facet arthropathy without spinal canal stenosis or neural foraminal narrowing.
Mild degenerative changes in the lumbar spine without significant spinal canal stenosis or clear evidence of nerve root impingement at any level. Minimal neural foraminal narrowing as described above.
