Low back pain radiating to bilateral lower extremities, hip flexion weakness Five lumbar type vertebral bodies are presumed to be present with the most inferior well-defined disc space labeled L5-S1. Vertebral body heights are within normal limits. Alignment is within normal limits. Bone marrow signal is benign. Multilevel degenerative changes are seen with disc desiccation and height loss at L5-S1 and to a lesser degree L4-L5 and L3-L4 levels. Edematous marrow signal changes are noted involving the endplates at the left L5-S1 level associated with disc height loss. The conus medullaris is normal in position.Individual levels as below:L1-L2: No spinal canal or neural foraminal stenosis.L2-L3: No spinal canal or neural foraminal stenosis.L3-L4: There is mild disc bulge, ligamentum flavum thickening, and facet arthropathy. There is no significant spinal canal stenosis. There is mild right neural foraminal narrowing. No significant left neural foraminal narrowing.L4-L5: There is disc bulge eccentric to the right, ligamentum flavum thickening, and moderate facet arthropathy as well as mild prominence of the dorsal epidural fat fat. There is resulting mild to moderate spinal canal stenosis. There is mild right neural foraminal stenosis. No significant left neural foraminal narrowing.L5-S1: Disc height loss with disc bulge and dorsal annular fissure. There is also ligamentum flavum thickening and moderate facet arthropathy. There is partial effacement of the bilateral recesses. There is mild central canal stenosis. There is moderate to severe left neural foraminal stenosis where there may be impingement of the exiting L5 nerve root. Right neural foramen is patent.
Multilevel degenerative changes in the lumbar spine with up to mild to moderate L4-L5 and mild L5-S1 spinal canal stenosis. There is also moderate to severe left L5-S1 neural foraminal stenosis where there may be impingement of the exiting L5 nerve root. Additional levels as described above.
