 5 lumbar type vertebral bodies are identified. The lumbar lordosis is preserved. The vertebral body heights and intervertebral disc spaces are grossly preserved. The osseous marrow signal is within normal limits. Mild inferior endplate degenerative changes demonstrated involving the L4 vertebral body with Schmorl's node which is slightly larger and associated with increased edema compared to prior. The conus is normal in signal and morphology and terminates at the T12-L1 level. The cauda equina appear unremarkable. There is congenital narrowing of the spinal canal. There is diffuse desiccation of the intervertebral discs of the lumbar spine.Individual levels as below:L1-L2: No significant spinal canal or neuroforaminal stenosis.L2-L3: There is a mild diffuse disc bulge however without neuroforaminal or spinal stenosis.L3-L4: There is a mild diffuse disc bulge causing moderate right and mild to moderate left neuroforaminal narrowing and mild spinal canal stenosis which is predominantly on the basis of developmental spinal canal narrowing. The previously seen disc extrusion at this level is no longer seen. L4-L5: There is a mild diffuse disc bulge at this level causing moderate left and mild to moderate right neural foraminal narrowing and mild spinal canal stenosis. L5-S1: There is a mild diffuse disc bulge at this level and advanced facet arthropathy. There is partial effacement of the right lateral recess as well as mild to moderate right neural foraminal stenosis. No significant central canal stenosis.
Developmental narrowing of the mid to lower lumbar spinal canal with superimposed degenerative changes as described above. There is mild spinal canal stenosis at the L3-L4 and L4-L5 levels. Additional details including neural foraminal narrowing as above.
