75-year-old female with radicular right lower extremity pain as well as hamstring weakness Marrow signal remains benign. The conus is normal in signal and morphology and terminates at an appropriate level. Redemonstrated is a gallstone, unchanged in appearance. A simple renal cyst is noted on the left, unchanged.L1/2: Asymmetric bulge to the left and bilateral mild facet hypertrophy with mild central canal stenosis with moderate left and mild right neural foraminal stenosis, unchanged.L2/3: Large Schmorl's node in the upper endplate of L3 and more extensive endplate degenerative bone marrow signal alterations. Diffuse annular disc bulge, ligamentum flavum thickening, prominent posterior epidural fat, and mild to moderate bilateral facet hypertrophy. There is moderate central, moderate bilateral lateral recess, and mild to moderate bilateral neural foraminal stenosis. Findings are unchanged.L3/4: There is a new/recurrent left paracentral disc extrusion which extends below the disc level causing new severe left lateral recess stenosis and now moderate to severe central stenosis. Residual underlying disc bulge, ligamentum flavum thickening, and mild to moderate bilateral facet hypertrophy with mild right and moderate left neural foraminal stenosis is unchanged. As before there is also evidence of Baastrup's disease.L4/5: There is unchanged grade 1 anterolisthesis of L4 on L5, a disc bulge, ligamentum flavum thickening, moderate to severe left facet hypertrophy, and moderate right facet hypertrophy. There is mild spinal canal and mild bilateral neural foraminal stenosis. There is also evidence of Baastrup's disease. These findings are stable.L5/S1: There is a mild disc bulge and mild left facet hypertrophy. No significant spinal canal stenosis or neuroforaminal narrowing. These findings are unchanged.
