IMPRESSION:
1. At L5/S1: Near complete loss of disc height with severe bilateral facet
arthropathy results in the moderate to severe bilateral foraminal stenosis and mild central canal stenosis. There is contact of the bilateral exiting L5
nerve roots and possible compression of the exiting right L5 nerve root.

2. Multilevel degenerative changes of the lumbar spine, most significant at
L4/5 as manifest by a circumferential disk bulge with markedly severe
bilateral facet arthropathy and moderate redundancy ligamentum flavum which results in mild to moderate bilateral foraminal stenosis.

The previously noted severe central canal stenosis now demonstrates moderate to severe central canal stenosis; as the previously noted central protrusion has partially resolved.

3. New 4 mm right central/paracentral disc protrusion with T2 hyperintense zones at L1/2 which partially effaces the right subarticular recess and contacts the traversing right L2 nerve root
