 Redemonstrated are postoperative changes from L2 through L5 with complete or partial laminectomy present. Two previously demonstrated spinal cord stimulators entering at T12/L1 and L1/2 are not well demonstrated with MRI technique and may has been removed. Correlation with x-ray or CT could help better define.Alignment is anatomic. There are no fractures or subluxations. The marrow signal is benign. The conus is normal in signal and morphology and terminates at an appropriate level. The visualized intra-abdominal and paraspinal contents are unremarkable.T12/L1: Bilateral facet hypertrophy without resulting stenosis, unchanged.L1/2: Mild disc bulge, ligamentum flavum thickening, and bilateral facet hypertrophy. There are no significant stenoses. These findings are unchanged.L2/3: Diffuse disc bulge, endplate spurring, facet hypertrophy, and presumed right incorporated posterior graft material. There is marked bilateral lateral recess and severe bilateral neural foraminal stenosis, unchanged.L3/4: Diffuse disc bulge, endplate spurring, facet hypertrophy, and presumed bilateral incorporated posterior graft material. There is mild central, marked bilateral lateral recess, and severe bilateral neural foraminal stenosis, unchanged.L4/5: Diffuse disc bulge, endplate spurring, facet hypertrophy, and presumed bilateral incorporated posterior graft material. There is severe central, marked bilateral lateral recess, and severe bilateral neural foraminal stenosis. Central and right foraminal stenosis have progressed. L5/S1:Asymmetric bulge to the right, endplate spurring, facet hypertrophy, and presumed bilateral incorporated posterior graft material. There is mild central, moderate right lateral recess, marked right lateral recess, mild left neural foraminal, and moderate to severe right neural foraminal stenosis, unchanged.SI Joints: Partial fusion with osteophytic bridging, unchanged.
