49-year-old female patient with low back pain, L5-S1. Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. Bone marrow signal is benign. The conus medullaris is normal in position.There is a grade 1 retrolisthesis of L5 on S1 with severe degenerative disc disease at this level. There is also disc narrowing and dessication at L3/L4 and L4/L5. There is underlying mid to distal lumbar developmental narrowing of the spinal canal due to short pedicles and dorsal epidural fat. Multilevel degenerative changes are as described below:L1-L2: No significant disc disease. No spinal canal or neural foraminal stenosis.L2-L3: No significant disc disease. No spinal canal or neural foraminal stenosis.L3-L4: Minimal posterior disc bulge, ligamentum flavum thickening, and facet hypertrophy contribute to minimal bilateral neural foraminal stenosis and mild central canal stenosis. There is a small central annular fissure.L4-L5: There is a small central annular fissure with a shallow central disc protrusion, ligamentum flavum thickening, and facet hypertrophy which contributes to mild bilateral neural foraminal stenosis. No spinal canal stenosis.L5-S1: Grade 1 retrolisthesis of L5 on S1 with disc uncovering and superimposed mild posterior disc bulge contributes to moderate to severe bilateral neural foraminal stenosis. No significant spinal canal stenosis. There is a left far lateral annular fissure. There is nodularity of the left partially imaged adrenal gland.
1. Grade 1 retrolisthesis of L5 on S1 with severe degenerative disc disease and moderate to severe bilateral neural foraminal stenosis at this level. Other findings including multilevel annular fissures as described above.2. Nodularity of the partially imaged left adrenal gland. Dedicated imaging may be obtained as clinically indicated.
