Right lower extremity weakness. For the purposes of numbering, there are 5 lumbar type vertebral bodies. The lumbar spine is in normal alignment, with a normal lumbar lordosis. The vertebral body and disk heights are well-maintained. No focal marrow signal abnormality is appreciated. 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 no significant compromise to spinal canal or neural foramina. Bilateral facet arthropathy.L2-L3: The spinal canal has been surgically decompressed with evidence of left-sided laminotomy. Mild disc bulge with minimal effacement of the thecal sac. No significant neural foraminal stenosis. Bilateral facet arthropathy.L3-L4: There is mild spinal canal narrowing, on a predominantly congenital basis. There is minimal prominence of epidural fat and mild right-sided neuroforaminal stenosis. Bilateral facet arthropathy.L4-5: Postsurgical changes of left-sided laminectomy and prior discectomy are noted. There is residual disc protrusion which may represent residual/recurrent disc herniation with associated mild to moderate degree of effacement of the thecal sac. There is no significant compromise to the neural foramina. Bilateral facet arthropathy.L5-S1: There is minimal disc bulge. Bilateral facet arthropathy. There is minimal bilateral neural foraminal stenosis. No significant spinal canal stenosis.There is a partially imaged right hip prosthesis noted.
Postsurgical changes of spinal canal decompression at L2-3 and L4-5 in addition to discectomy at L4-5. There is evidence of residual/recurrent disc herniation at L4-5 with mild to moderate effacement of the thecal sac at this level. There is no high-grade spinal canal or high-grade neuroforaminal stenosis at any level.
