Right foot drop, lower extremity pain. Patient has MRI compatible spinal cord stimulator device. For the purposes of numbering, there are 7 cervical, 12 thoracic, and 4 lumbar type vertebral bodies, which is consistent with prior CT lumbar spine reports. The last rib-bearing vertebra is labeled T12.Partially imaged cervical spine demonstrates a disc herniation at the C3-C4 level on the sagittal images with mass effect on the ventral cervical cord which is not well evaluated. Small disc osteophyte complexes at the C4-C5 and C5-C6 levels are also present.Thoracic: There is a central disc protrusion at the T7-T8 level which effaces the ventral thecal sac and is associated with impression on the ventral aspect of the thoracic cord. There is overall mild to moderate degree of spinal canal stenosis at this level with some residual CSF space dorsally.Vertebral body heights and alignment of the thoracic spine are otherwise normal. Bone marrow signal is benign. No significant herniation, spinal canal stenosis, or neural foraminal stenosis is evident at the remainder of the thoracic spine levels. There is mild to moderate multilevel facet arthropathy in the lower thoracic spine.Lumbar: As mentioned above, there are 4 lumbar type vertebral bodies, which is consistent with prior CT lumbar spine reports. The last rib-bearing vertebra is labeled T12. Vertebral body heights are within normal limits. There is grossly unchanged appearance of the grade 1 anterolisthesis of L3 on L4 with evidence of interspinous fixation device at this level as seen on prior CT. Bone marrow signal is benign. Multilevel degenerative changes are seen, as described below:L1-L2: Minimal disc bulge, ligamentum flavum thickening, and facet arthropathy. No significant spinal canal or neural foraminal stenosis.L2-L3: Minimal disc bulge, ligamentum flavum thickening, and facet arthropathy. There is mild to moderate left neural foraminal stenosis. No significant spinal canal or right neural foraminal stenosis.L3-L4: Postoperative changes with interspinous fixation device better seen on prior CT. There is advanced facet arthropathy and bony proliferation along the ligament of flavum which contributes to mild to moderate spinal canal stenosis. There is disc uncovering and disc bulge which extends into the right neural foramen. There is associated moderate degree of right-sided neural foraminal stenosis. Left neural foramen is patent. L4-S1: Mild disc bulge and facet arthropathy. No spinal canal stenosis. Minimal narrowing of the neural foramina.
1. For the purposes of numbering, there are 7 cervical, 12 thoracic, and 4 lumbar type vertebral bodies, which is consistent with prior CT lumbar spine reports. The last rib-bearing vertebra is labeled T12.2. T7-T8 central disc extrusion with minimal craniocaudal extension. There is effacement of the ventral thecal sac and mild impression on the ventral thoracic cord. No cord signal abnormality. Otherwise no significant spinal canal or neural foraminal stenosis in the thoracic spine.3. Postoperative changes of interspinous fusion at L3-L4 with unchanged grade 1 anterolisthesis. There is mild to moderate degree of spinal canal stenosis at this level related to facet arthropathy and bony proliferation along the ligamentum flavum. There is also moderate right-sided neural foraminal stenosis where there may be impingement of the exiting right-sided nerve root.4. Mild to moderate left L2-L3 neural foraminal stenosis.5. C3-C4 disc herniation partially imaged on the sagittal localizer sequence with suggestion of mass effect on the ventral cord at this level.
