 For the purposes of labeling, the last rib-bearing vertebra is designated T12. The L5 vertebra appears sacralized. The lumbar spine is in normal alignment, with a normal lumbar lordosis. The vertebral body heights are well-maintained without evidence of compression fracture. There is disc desiccation with moderate loss of disc height at L3-L4. No worrisome focal marrow signal abnormality is appreciated. The distal spinal cord and conus are within normal limits with the conus terminating at the T12-L1 level.T10-T11 (sagittal images only): Small right perineural cyst. No significant disc bulge, spinal canal stenosis. T11-T12: Bilateral perineural cysts. No significant disc bulge or spinal canal stenosis. T12-L1: Bilateral perineural cysts. No significant disc bulge or spinal canal stenosis. L1-L2: No significant disc bulge, spinal canal or foraminal stenosis. L2-L3: Bilateral perineural cysts, mild disc bulge, bilateral facet degeneration and thickening of the ligamentum flavum. No significant spinal canal or foraminal stenosis. L3-L4: Disc bulge with superimposed left paracentral disc extrusion and superior migration of 13 mm, bilateral facet degeneration and thickening of the ligamentum flavum, contributing to mild left foraminal stenosis. No significant spinal canal or right foraminal stenosis. L4-L5: Mild disc bulge, bilateral facet degeneration and thickening of the ligamentum flavum. No significant spinal canal or foraminal stenosis. L5-S1: No significant disc bulge, spinal canal or foraminal stenosis.
1. No compression fractures. Mild degenerative changes of the lumbar spine as detailed above. There is a left paracentral disc extrusion at L3-L4 with superior migration of 13 mm. There is mild left L3-4 foraminal stenosis. Spinal canal and neural foramina in the lumbar spine are otherwise patent. 2. Multiple small perineural cysts are incidentally noted and of doubtful clinical significance.3. Transitional lumbosacral anatomy as detailed above.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
