Lumbar radiculopathy For the purposes of numbering, the last rib-bearing vertebra is labeled T12. There are 5 lumbar type vertebral bodies and a sixth lumbarized transitional segment labeled L6 for the purposes of this study. Vertebral body heights are within normal limits. There is levoscoliosis of the lumbar spine. Bone marrow signal is benign. Small Schmorl's nodes are noted involving the endplates at multiple levels. There is multilevel disc desiccation with particular height loss at the L2-L3 and L3-L4 levels. The conus medullaris is normal in position.Multilevel degenerative changes are seen, as described below:L1-L2: No significant disc disease. No spinal canal or neural foraminal stenosis.L2-L3: Loss of disc height. There is minimal bulge eccentric to the left with no significant spinal canal stenosis. There is minimal left neural foraminal narrowing. No significant right neural foraminal stenosis. L3-L4: Disc desiccation with minimal bulge. There is bilateral facet arthropathy. There is minimal right neural foraminal narrowing. No spinal canal or left neural foraminal stenosis.L4-L5: Mild disc bulge and bilateral facet arthropathy. There is minimal right neural foraminal narrowing. There is no significant spinal canal or left neural foraminal stenosis. L5-L6: There is advanced bilateral facet arthropathy with an ovoid epidural lesion involving the left lateral aspect of the spinal canal most consistent with a synovial cyst. This lesion measures 10 mm in the AP dimension and up to 14 mm in the craniocaudal dimension. Lesion is associated with effacement of the left lateral recess and possible impingement of the descending nerve root at this level. There is also mild mass effect on the left lateral aspect of the thecal sac. There is mild disc bulge. There is mild left neural foraminal stenosis. No significant right neural foraminal narrowing.L6-S1: No significant disc disease. No spinal canal or neural foraminal stenosis. Bilateral facet arthropathy.Paraspinous soft tissues are within normal limits. Small cysts in the kidneys are incidentally noted.
1. Please note transitional lumbosacral anatomy with numbering of the vertebral bodies as L1 through L6.2. Multilevel degenerative changes in the lumbar spine. There is levoscoliosis which can be further assessed with standing radiographs. 3. There is a synovial cyst in the left lateral epidural space at the L5-L6 level measuring 10 x 14 mm (APxcraniocaudal) and is associated with effacement of the left lateral recess as well as mild mass effect on the left lateral aspect of the thecal sac. This lesion may be contributing to left-sided radicular symptoms. Please see additional details above.
