 Vertebral body heights are preserved. Again seen is severe levoscoliosis of the lumbar spine with apex at the L1-L2 level which can be better assessed on radiographs. There is mild rightward subluxation of T12 on L1 and L1 on L2. Bone marrow signal is benign. A small 11 mm left S2 Tarlov cyst is again noted. Multilevel degenerative changes are again seen. Differences in axial planes related to scoliosis makes comparison difficult.L1/2: There is disk bulge eccentric to the right. There is effacement of the right lateral recess and severe right neural foraminal stenosis. There are severe endplate changes on the right with mild right lateral subluxation of L1 on L2. No significant central spinal canal or left neural foramina narrowing.L2/3: There is disk bulge eccentric to the right with partial effacement of the right lateral recess and severe right neural foraminal stenosis. There is hypertrophy of the ligamentum flavum and facet joint on the right side, contributing to the right neural foraminal narrowing. No significant spinal canal stenosis. There is minimal left neural foramina narrowing related to disk bulge.L3/4: There is mild diffuse disk bulge with severe right neural foramina stenosis. There is mild left neural foramina stenosis. No significant spinal canal stenosis.L4/5: Diffuse disk bulge asymmetric to the left with severe left neural foramina stenosis again demonstrated. There is prominent left-sided facet arthropathy which also contributes. There is mild central spinal canal stenosis related to ligamentum flavum thickening. L5/S1: Mild central disk protrusion. No significant spinal canal stenosis or foraminal narrowing.
1. Multilevel degenerative changes with severe levoscoliosis of the lumbar spine with apex at the L1-L2 level.2. There is no high-grade spinal canal stenosis at any level.3. Severe neural foramina stenosis at right L1-L2, right L2-L3, right L3-L4, and left L4-L5 levels.
