Findings:
Scoliosis with a primary lumbar curvature to the left and a secondary thoracic curvature to the right.
The vertebral bodies are of normal height with no malalignment.
There is diffuse osteopenia and degenerative changes, in special within the L1/2, L4/5 and L5/S1 levels, in which prominent intervertebral osteochondrosis are noted with irregularities and subchondral sclerosis involving the endplates, marginal osteophytes, and disc degeneration with gas.
L1/2: Osteochondrosis as previously described. Minimal disc bulging with associated posterior osteophytes, mildly indenting the dural sac without any significant stenosis.
L2/3 and L3/4: Mild posterior disc bulging indenting the dural sac anteriorly. No foraminal impingement.
L4/5: Osteochondrosis as previously described. Disc bulging associated with osteophytes, without any central canal stenosis. Additional osteoarthritis of the facet joints with moderate neural exit foraminal stenosis at this level on the left, without obvious nerve root impingement.
L5/S1: Osteochondrosis as previously described. Broad-based, posterior disc bulging and bilateral osteoarthritis of the facet joints, more significant on the left side with high-grade neural exit foraminal stenosis at this level on the left, possibly affecting the left L5 nerve root.
Tarlov cysts are seen with enlargement of the S2 neural exit foramina bilaterally.
Mild-to-moderate degenerative changes of the sacroiliac joints are seen bilaterally.
Moderate atherosclerotic changes of the abdominal aorta and the iliac arteries are seen. No paravertebral abnormality is identified.
Conclusion:
Scoliotic deformity and moderate spondylodegenerative changes of the lumbar spine, as described above, with high-grade neural exit foraminal stenosis at L5/S1 on the left. No significant central canal stenosis.
