Female, 69 years old. Left-sided low back pain with left-sided sciatica. Five lumbar type vertebral bodies are presumed to be present. The lumbar spine shows leftward thoracolumbar scoliosis more clearly demonstrated on recent radiographs. The vertebral body and disk heights are well-maintained. No focal marrow signal abnormality is appreciated. The conus medullaris on sagittal imaging is grossly intact, terminating at approximately the L1 level. The paraspinal soft tissues are unremarkable.T12-L1: There is no significant compromise to spinal canal or neural foramina.L1-L2: There is no significant compromise to spinal canal or neural foramina.L2-L3: There is diffuse disc bulge and mild facet hypertrophy with mild right neural foraminal narrowing and no significant spinal canal stenosis.L3-L4: There is diffuse disc bulge and mild facet hypertrophy with mild right neural foraminal narrowing and no significant spinal canal stenosis.L4-5: There is grade 1 anterolisthesis of L4 over L5 with disc uncovering, diffuse disc bulge which is slightly more prominent posterolaterally toward the left neural foramen, as well as ligamentum flavum hypertrophy and facet hypertrophy, left greater than right, with severe left neural foraminal narrowing, mild right neural foraminal narrowing, as well as mild spinal canal stenosis.L5-S1: There mild facet hypertrophy with no significant compromise to spinal canal or neural foramina.
Degenerative changes involving the lumbar spine, most severe at the L4-5 level with severe left neural foraminal narrowing and mild spinal canal stenosis at this level. Up to mild neural foraminal narrowing at other levels.
