 There is straightening of the normal lumbar lordosis. There is mild anterolisthesis of L3 on L4 of approximately 5 mm and minimal anterolisthesis of L5 on S1, which are likely on a degenerative basis. There is progression of mild to moderate loss of disc height throughout the lumbar spine with disc desiccation, especially at L2-L3. The vertebral body heights are well-maintained. The marrow signal is heterogeneous. There is no pathological enhancement. The distal spinal cord and conus are within normal limits with the conus terminating at the L1 level. The partially imaged kidneys demonstrate bilateral renal cysts.T12-L1: Interval development of disc bulge with superimposed central disc extrusion with inferior migration of 7 mm. No significant spinal canal or foraminal stenosis.L1-L2: Progression of disc bulge with superimposed central disc extrusion and superior migration of 11 mm and mild bilateral facet degeneration. No significant spinal canal or foraminal stenosis. L2-L3: Progression of disc bulge with bilateral facet degeneration and thickening of the ligamentum flavum, contributing to mild right and moderate left neuroforaminal stenosis. No significant spinal canal stenosis.L3-L4: Unchanged mild anterolisthesis of L3 and L4 with pseudodisc bulge, advanced bilateral facet degeneration and thickening of the ligamentum flavum contributing to effacement of the lateral recesses, mild to moderate spinal canal stenosis and moderate bilateral neuroforaminal stenosis (left worse than right). There is enhancing epidural tissue at the L3 level effacing the right posterolateral thecal sac, which is likely related to granulation tissue.L4-L5: Slight progression of disc bulge, asymmetric to the right, with central disc protrusion and bilateral facet degeneration, contributing to mild bilateral foraminal stenosis and minimal spinal canal narrowing. There is slightly progressed effacement of the right lateral recess with possible impingement on the descending right L5 nerve root.L5-S1: Unchanged disc bulge with bilateral facet degeneration, contributing to moderate right greater than left foraminal stenosis. No significant spinal canal stenosis.
1. Moderate degenerative changes of the lumbar spine with progression of degenerative disc disease at the L1-L2, L2-L3 and L4-L5 levels with mild to moderate spinal canal stenosis at L3-L4. There is effacement of the right lateral recess at L4-5 slightly worse than prior which may be impinging on the traversing right L5 nerve root. There is also foraminal stenosis at multiple levels as detailed above.2. No suspicious lesions to suggest metastatic disease.
