Back and leg pain, neurogenic medication Five lumbar type vertebral bodies are presumed to be present which are appropriate in overall height. There is grade 1 anterolisthesis at L4-5 which is not significantly changed. Alignment is otherwise maintained. There is vacuum phenomena at the L4-L5 and L5-S1 levels is stable to slightly increased since prior. Bone marrow signal is benign.Degenerative changes further described below:At L1-2 there is no significant compromise to spinal canal or neural foramina. Mild facet arthropathy. At L2-3 there is no significant compromise to spinal canal or neural foramina. Mild facet arthropathy. Minimal disc bulge.At L3-4 there is no significant compromise to spinal canal or neural foramina. Bilateral facet arthropathy. Minimal disc bulge.At L4-5 there is grade 1 anterolisthesis, disc dessication, disc uncovering as well as tiny extrusion superimposed on disc bulge similar to prior. There is also advanced facet arthropathy and evidence of prior decompressive left hemi-laminectomy. There is mild to moderate left and mild right neural foraminal stenosis minimally worse since 6/2/2015. No significant spinal canal stenosis. At L5-S1 there is mild disc bulge similar to prior along with advanced facet arthropathy, right greater than left. Previously seen distention within the right facet joint has decreased. There is moderate to severe right neural foraminal stenosis which appears slightly worse. Left neural foramen and spinal canal remain patent.18 x 17 mm T2 hyperintense lesion involving the right kidney again seen and better characterized on prior postcontrast CT studies.
1. Again seen are degenerative changes in the lumbar spine at the L4-L5 and L5-S1 levels with vacuum phenomena which are stable to minimally progressed since 6/2/2015. Grade 1 anterolisthesis at L4-L5 appears similar to prior. There is no significant spinal canal stenosis at any level. 2. There is moderate to severe right L5-S1, mild to moderate left L4-L5, and mild right L4-L5 neural foraminal stenosis. 3. There is advanced facet arthropathy at the L4-L5 and L5-S1 levels.4. Prior left L4-5 hemilaminectomy.
