Female, 61 years old, with history of lumbar osteoarthritis and new right proximal leg weakness. Maintaining the previously utilized numbering scheme, the L1 vertebral body bears rudimentary ribs.A mild scoliotic curvature of the lumbar spine is seen. In the sagittal plane, the lumbar lordosis is mildly straightened but alignment is otherwise unremarkable.Vertebral body height and morphology are normal allowing for endplate degenerative irregularity and signal change at most levels. No evidence of concerning marrow replacement or marrow edema is seen.The visualized spinal canal, conus and cauda equina are unremarkable.Multilevel disc degeneration with loss of height and T2 signal is again seen similar to prior. Additional level specific findings are as follows:L1-2: Mild facet hypertrophy and ligamentum flavum thickening. Mild bulging disc. No significant generalized spinal canal stenosis. No significant neuroforaminal narrowing. No significant interval changes.L2-3: Moderate facet hypertrophy and ligamentum flavum thickening. Mild bulging disc asymmetric to the right. No significant generalized spinal canal stenosis. No significant spinal canal stenosis. Moderate right foraminal narrowing. No significant interval changes.L3-4: Moderate facet hypertrophy and ligamentum flavum thickening, right greater than left. Moderate bulging disc asymmetric to the right. Moderate generalized spinal canal stenosis. Moderate right and mild left foraminal narrowing. No significant interval changes.L4-5: Severe facet hypertrophy and ligamentum flavum thickening. Moderate bulging disc. Moderate generalized spinal canal stenosis. Severe left and moderate right foraminal narrowing. No significant interval changes.L5-S1: Moderate facet hypertrophy. Mild bulging disc. No significant generalized spinal canal stenosis. Moderate bilateral foraminal narrowing. No significant interval changes.A left renal cystic lesion is again seen.
No significant interval change in multilevel degenerative disease as detailed above.
