 The last well formed disk space is referred to as L5-S1. There is normal alignment of the lumbar spine. There are type II endplate degenerative changes at L4-5, along with mild reactive edema in the L4-5 disk. There is moderate loss of T2 signal in L4-5 disk with mild loss of disk height. There is mild loss of T2 signal in all other lumbar disks without significant loss of disk height at any other level. The conus terminates at L1-2 and shows normal caliber and signal.T11-12: No disk herniation or spinal stenosis.T12-L1: No disk herniation or spinal stenosis.L1-2: Right far lateral disk protrusion without significant spinal canal or neural foraminal stenosis.L2-3: Minimal diffuse disk bulge, moderate bilateral facet arthropathy and ligamentum flavum thickening causing no significant neural foraminal or spinal canal stenosis.L3-4: Mild disk bulge with central annular fissure, moderate bilateral facet arthropathy and ligamentum flavum thickening causing no significant spinal canal or neural foraminal stenosis.L4-5: Diffuse disk bulge, moderate bilateral facet arthropathy causing no significant spinal canal stenosis. There is mild right and minimal left neural foraminal stenosis, with disk material approaching the right exiting L4 nerve root in the neural foramen.L5-S1: Diffuse disk bulge, mild facet arthropathy with no significant spinal canal stenosis or neural foraminal stenosis.
1.Type II endplate degenerative changes at L4-5 with mild reactive degenerative edema in the L4-5 disk. Mild right and minimal left neural foraminal stenosis at L4-5, with disk material approaching the right exiting L4 nerve root in the neural foramen.2.Moderate multilevel facet degenerative disease as described above.
