 The last well formed disk space is referred to as L5-S1. There is 4-mm retrolisthesis of L5 on S1. There is no osseous marrow edema. The conus terminates at L1.T12-L1: No spinal stenosis or disk herniation.L1-2: No disk herniation or spinal stenosis.L2-3: Mild disk bulge and facet arthropathy with no spinal stenosis.L3-4: Disk desiccation with moderate loss of disk height, and mild disk bulge with no significant spinal stenosis.L4-5: Disk desiccation with moderate loss of disk height, moderate bilateral facet arthropathy causing mild bilateral neural foraminal stenosis and no significant spinal canal stenosis.L5-S1: Disk desiccation with severe loss of disk height, type II endplate degenerative changes, retrolisthesis of L5 on S1 causing no significant spinal canal stenosis and mild bilateral neural foraminal stenosis.There is a right renal cyst incompletely imaged measuring up to 18 mm.
1.Multilevel lumbar spondylosis with mild bilateral neural foraminal stenoses at L4-5 and L5-S1.2.Incompletely imaged right renal cyst measuring up to 18 mm.
