56-year-old male with back pain. Evaluate T12-L1 disc herniation. At T12-1, there is a disc herniation eccentric to the right with mild to moderate neural foraminal narrowing, but no significant spinal canal stenosis. The patient is status post left-sided hemilaminectomy at L5. At L5-S1, there is loss of disc space height, disc desiccation, and disc bulge associated with bilateral neural foraminal narrowing, moderate on the right and severe on the left. There is effacement of the left lateral recess. There is no significant compromise to spinal canal. At L4-5, there is loss of disk space height, disk bulge, disk desiccation and ligamentum flavum hypertrophy with apparent impingement of nerve roots in the left lateral recess and mild neural foraminal narrowing bilaterally. At L1-4, there is no significant narrowing of the spinal canal or neural foramina. The vertebral column alignment is within normal limits. The imaged portions of the spinal cord are unremarkable. There are incompletely characterized bilateral renal T2 hyperintense lesions, which likely represent cysts.
1. A disc herniation eccentric to the right at T12-L1 results in mild to moderate neural foraminal narrowing.2. Postsurgical findings and persistent degenerative spondylosis in the lower lumbar spine, most pronounced at L5-S1.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
