Female, 63 years old, with intermittent radicular pain down the right lower extremity more than the left lower extremity. A transitional morphology of the L5 vertebral body is seen. Spinal alignment is anatomic. Vertebral body morphology and marrow signal characteristics are within normal limits.Visualized spinal cord and conus are unremarkable. The cauda equina dispersed evenly through the thecal sac.L1-2: Unremarkable. L2-3: Mild facet arthropathy. Mild laterally bulging disc. No spinal canal stenosis. Mild neuroforaminal narrowing. No significant interval changes. L3-4: Moderate facet arthropathy and ligamentum flavum thickening. The previously seen large left lateral recess disc extrusion has resolved with relief of previously seen lateral recess narrowing and nerve impingement. Mild residual bulging disc is seen with perhaps a minimally progressive focal component within the left neural foramen. No significant spinal canal stenosis. Moderate left foraminal narrowing, slightly progressed from the prior examination. Mild right foraminal narrowing, unchanged. L4-5: Moderate facet arthropathy and ligamentum flavum thickening. Mild bulging disc with a small superimposed central protrusion, stable. Moderate spinal canal stenosis, stable. Mild bilateral foraminal narrowing, stable. L5-S1: Unremarkable.
1.Interval resolution of the previously seen large left lateral recess disc extrusion spanning the L3 vertebral body. Previously seen lateral recess stenosis and nerve root impingement has been relieved.2.Minimal progression of a very small left foraminal disc protrusion at L3-4 which results in mild worsening of the foraminal narrowing.3.Disc and posterior element degeneration at L4-5 resulting in a moderate generalized spinal canal stenosis, unchanged.
