Male, 57 years old. Low back pain radiating down the leg. Five lumbar type vertebral bodies are presumed to be present. The lumbar spine is in normal alignment, with a normal lumbar lordosis. The vertebral body heights are well-maintained. There is nonspecific diffuse marrow heterogeneity, without focal abnormality. The conus medullaris on sagittal imaging is grossly intact.T12-L1: There is no significant compromise to spinal canal or neural foramina.L1-L2: There is mild disc bulge with an annular fissure in the left foraminal/far lateral region with perhaps early left paracentral to foraminal shallow protrusion. There is no significant compromise to spinal canal or neural foramina.L2-L3: There is mild disc bulge and mild bilateral facet hypertrophy, with focal bilateral foraminal prominence. There is mild left and mild to moderate right neural foraminal narrowing, and the focal left distal foraminal disc prominence abuts the exiting left L2 nerve root. There is no significant central canal stenosis. L3-L4: There is diffuse disc bulge and mild facet hypertrophy with more focal prominence in the right paracentral/foraminal region. The descending right L4 nerve root is minimally displaced posteriorly, and the exiting right L3 nerve root is approached by the focal foraminal disc prominence. There is moderate right and mild left neural foraminal narrowing, and mild central canal stenosis.L4-5: There is moderate facet hypertrophy and disc narrowing with diffuse disc bulge. There is more focal prominence along the right foraminal region, with mild bilateral neural foraminal narrowing and mild central canal stenosis.L5-S1: There is moderate facet hypertrophy with mild to moderate bilateral neural foraminal narrowing.
Degenerative changes of the lumbar spine as described above. At L2-3, focal left disc prominence abuts the exiting left L2 nerve root. At L3-4, the exiting right L3 nerve root is approached by the focal foraminal disc prominence, and the descending right L4 nerve root is minimally displaced posteriorly.
