 The last well formed disk space is referred to as L5-S1. Marrow signal is benign. There is no spondylolisthesis. There is loss of T2 signal in the L5-S1 disk. The conus terminates at L2 and shows normal caliber and signal. There are tiny hepatic T2 hyperintensity foci likely representing cysts.T11-12: No spinal stenosis.T12-L1: Mild disk bulge with no spinal stenosis.L1-2: No disk herniation or spinal stenosis.L2-3: No disk herniation or spinal stenosis. Mild ligamenta flava thickening and facet arthropathy.L3-4: Mild disk bulge, ligamenta flava thickening and facet arthropathy with no spinal stenosis.L4-5: Mild disk bulge, ligamenta flava thickening and facet arthropathy with no spinal canal stenosis and minimal left neural foraminal stenosis.L5-S1: Mild disk bulge, moderate ligament flava thickening and facet arthropathy causing no significant spinal canal stenosis and mild bilateral neural foraminal stenosis. Mild edema in the bilateral L5-S1 pedicles and facets with a small right L5-S1 facet effusion.
Bilateral L5-S1 facet arthrosis with small right facet effusion, and reactive mild edema in the bilateral L5, and S1 pedicles and facets. Mild bilateral L5-S1 neural foraminal stenosis.
