Reason: eval lumbar spine, known spondylosis History: back pain Using the last set of ribs as guidance, there are 4 lumbar type vertebral bodies with a sacralized L5. There is grade 1 retrolisthesis of L4 over L5. Loss of disc height is seen at the L4/5 level. Otherwise vertebral body heights and disc heights are maintained. There is degenerative endplate signal abnormalities at L4/5, otherwise bone marrow signal is unremarkable. Normal-appearing conus terminates at L1/2 level. Right renal cyst is noted. Otherwise visualized intra-abdominal and paraspinal structures appear unremarkable.T12/L1: No significant spinal canal stenosis or foraminal narrowing.L1/2: No significant spinal canal stenosis or foraminal narrowing.L2/3: Desiccated disc with mild lateral disc bulge. Mild facet arthropathy with ligamentum flavum thickening. No significant spinal canal stenosis. Mild bilateral foraminal narrowing.L3/4: Lateral disc bulge, facet arthropathy, and ligamentum flavum thickening resulting in mild spinal canal stenosis and mild bilateral foraminal narrowing.L4/5: Degenerative endplate changes of the bone marrow. Loss of disc height with desiccation of the disc. Uncovering of the disc posteriorly due to retrolisthesis with bulging disc symmetric to the right foraminal region. Moderate facet arthropathy with ligamentum flavum thickening. Mild to moderate spinal canal stenosis particularly affecting the lateral recesses. Severe right and moderate left foraminal narrowing.L5/S1: No significant spinal canal stenosis or foraminal narrowing.
Grade 1 retrolisthesis of L4 over L5. Degenerative changes of the lumbar spine most severe at the L4-5 level.
