 Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. Alignment is within normal limits. Bone marrow signal is benign. The conus medullaris is normal in position. Mild disc desiccation is seen at L2-3, L3-L4, L4-5 and L5-S1 levels. There is prominent epidural fat involving most on the lumbar levels resulting in developmental narrowing of the distal spinal cord. Multilevel degenerative changes are seen, as described below:L1-L2: There is mild ligamentum flavum thickening and left facet hypertrophy. No spinal canal or neural foraminal stenosis.L2-L3: No significant disc disease. No spinal canal or neural foraminal stenosis.L3-L4: There is ligamentum flavum thickening. No spinal canal or neural foraminal stenosis.L4-L5: There is mild disc bulging causing mild to moderate bilateral foraminal stenosis. There is ligamentum flavum hypertrophy. Moderate facet arthropathy is noted. No spinal canal stenosis.L5-S1: There is disc bulge with left more than right causing moderate left foraminal stenosis. There is bilateral facet hypertrophy. No spinal canal stenosis.Paraspinous soft tissues are within normal limits. Partly imaged rounded T2 bright lesion is seen in the upper medial cortex of the right kidney likely related to a cyst as seen on previous abdominal CT.
1. Mild to moderate multilevel degenerative disc disease predominantly affecting L5-S1 causing moderate left foraminal stenosis. Mild to moderate bilateral foraminal stenosis is seen at L4-L5 level.2. Prominent epidural lipomatosis without definite evidence of spinal canal stenosis.
