Lower extremity weakness, numbness. Rule out infection/compression. Five lumbar type vertebral bodies are presumed to be present. Hypoplastic ribs are present at T12. There is transitional anatomy involving the L5 level with pseudoarticulation involving the right L5 transverse process with the sacrum, better seen on recent CT abdomen. Vertebral body heights are within normal limits. There is minimal retrolisthesis of L1 on L2 and L3 on L4 and minimal anterolisthesis of L4 on L5. Bone marrow signal is benign. The conus medullaris is normal in position. No abnormal enhancement involving the cauda equina nerve roots. No edema or abnormal enhancement to suggest discitis-osteomyelitis or epidural abscess. No paraspinous fluid collections.Multilevel degenerative changes are seen, as described below:L1-L2: Mild disc bulge, ligamentum flavum thickening, and facet arthropathy. No spinal canal or neural foraminal stenosis.L2-L3: Mild disc bulge, ligamentum flavum thickening, and facet arthropathy. No spinal canal or neural foraminal stenosis.L3-L4: Disc bulge with small central protrusion, mild facet arthropathy, and ligamentum flavum thickening. There is no significant spinal canal stenosis. There is mild bilateral neural foraminal stenosis.L4-L5: Mild disc bulge, ligamentum flavum thickening, and advanced bilateral facet arthropathy. No significant spinal canal stenosis. There is mild to moderate bilateral neural foraminal stenosis.L5-S1: No significant disc disease. Mild to moderate facet arthropathy. Pseudoarticulation involving the right L5 transverse process and the sacrum noted. No significant spinal canal or neural foraminal stenosis.
1. No findings to suggest infection in the lumbar spine. Specifically, no discitis-osteomyelitis, epidural abscess, or paraspinous abscess.2. Multilevel degenerative changes as detailed above without high-grade spinal canal stenosis at any level.
