Spinal stenosis lumbar region. Neurogenic claudication. Idiopathic scoliosis and kyphoscoliosis. There is straightening of lumbar lordosis. Five lumbar type vertebral bodies are presumed to be present. Vertebral body heights are within normal limits. There is moderate narrowing of the L2-L3 through L4-L5 discs with disc desiccation. Alignment is within normal limits. Bone marrow signal is benign. The conus medullaris is normal in position.There is increased dorsal epidural fat throughout the lumbar spine contributing to spinal stenosis. Multilevel degenerative changes are seen, as described below. L1-L2: There is left far lateral disc protrusion which is similar compared to the previous exam. No definite foraminal stenosis. No central spinal canal stenosis.L2-L3: There is eccentric left disc bulge causing partial narrowing of the left neural foramen. There is right paracentral disc bulge indenting the thecal sac anteriorly. Mild to moderate central canal stenosis is evident. There is facet arthropathy and ligamentum flavum thickening.L3-L4: Severe endplate degenerative changes are present. There is diffuse disc bulge slightly prominent to the right side causing mild to moderate right foraminal narrowing and mild to moderate left foraminal narrowing. There is moderate central spinal canal stenosis at this level. These findings are likely progressed compared to the previous exam. There is facet arthropathy and ligamentum flavum thickening.L4-L5: Severe endplate degenerative changes are present. Prominent left disc bulge is noted. There is mild central spinal canal stenosis. There is facet arthropathy and ligamentum flavum thickening. Lateral recess narrowing is again noted greater on the left.L5-S1: No significant disc disease. No spinal canal or neural foraminal stenosis. There is facet arthropathy and ligamentum flavum thickening.Paraspinous soft tissues are within normal limits.Rounded T2 hyperintensities are noted in the bilateral kidneys which are nonspecific but most likely represent cysts.
1.Multilevel lumbar spondylotic changes with findings most conspicuous and minimally progressed at L3-L4 resulting in moderate central spinal canal stenosis as well as mild to moderate left and mild right foraminal stenosis.2.Rounded T2 hyperintense areas in the bilateral kidneys statistically representing cysts. Ultrasound of the abdomen can be obtained if further indicated.
