 Cervical spine:There has been prior anterior cervical fusion at C5, C6, and C7 better visualized on previous cervical spine CT.Redemonstrated is congenital narrowing of the spinal canal.Alignment is anatomic. There are no fractures or subluxations. The marrow signal is benign. The cervical cord is normal in signal. The cervicomedullary junction is normal. The cerebellar tonsils are in normal position. The visualized paraspinal contents are unremarkable.C2/3: Previously demonstrated minimal anterolisthesis is again noted. Mild disc bulge as well as facet and uncovertebral proliferative change is present resulting in moderate left neural foraminal stenosis.C3/4: Posterior osteophyte disc complex, uncinate hypertrophy, and facet hypertrophy. There is mild/moderate central and moderate bilateral neural foraminal stenosis.C4/5: Posterior osteophyte disc complex asymmetric to the right, bilateral uncinate hypertrophy, ligamentum flavum thickening, and bilateral facet hypertrophy. The cord is flattened both anteriorly and posteriorly, worse on the right anteriorly, demonstrating intrinsic cord T2 hyperintensity of myelomalacia. There is moderate central and moderate bilateral neural foraminal stenosis.C5/6: Right uncinate hypertrophy causes mild-to-moderate right neural foraminal stenosis.C6/7: Bilateral uncinate hypertrophy (right greater than left) and causes mild left and mild-to-moderate right neural foraminal stenosis.C7/T1: Mild bilateral facet are particular without stenosis.Thoracic spine:There is a smooth, physiologic thoracic kyphotic curve. The vertebral body heights and disc spaces are maintained. Marrow signal intensity is benign throughout. A benign hemangioma is present within the T11 vertebral body. T1/2 demonstrates no significant disc bulge or cord encroachment.T2/3 demonstrates a shallow right paracentral disc protrusion causing minimal anterior right hemicord flattening without intrinsic cord signal abnormality or stenosis.T3/4 demonstrates a minimal right shallow paracentral disc protrusion without cord encroachment. T4/5 demonstrates no significant disc bulge or cord encroachment. T5/6 demonstrates no significant disc bulge or cord encroachment.T6/7 demonstrates no significant disc bulge or cord encroachment. T7/8 demonstrates a shallow central disc protrusion without cord encroachment. T8/9 demonstrates a shallow right paracentral disc protrusion without cord encroachment. T9/10 demonstrates no significant disc bulge or cord encroachment.T10/11 demonstrates no significant disc bulge or cord encroachment. T11/12 demonstrates a shallow right paracentral disc protrusion without cord encroachment. T12/L1 demonstrates no significant disc bulge or cord encroachment. Lumbar spine:As been prior L5 laminectomy with a disc spacer at L5/S1, better demonstrated on previous CT.There are no acute fractures. The marrow signal is benign. The conus is normal in signal and morphology and terminates at an appropriate level. The visualized intra-abdominal and paraspinal contents are unremarkable.Redemonstrated is grade 1 anterolisthesis L5 on S1, grade 1, minimal retrolisthesis of L2 on L3, minimal retrolisthesis L3 on L4, and grade 1 anterolisthesis L4 on L5. These findings are unchanged.L1/2: Mild bilateral facet hypertrophy without stenosis.L2/3: Mild disc bulge and mild bilateral facet hypertrophy without stenosis.L3/4: Mild disc bulge and mild-to-moderate bilateral facet hypertrophy without stenosis.L4/5: Diffuse annular disc bulge, severe facet hypertrophy associated with what appears to be bilateral bone graft material. Residual facets demonstrate bilateral effusions. There is associated reactive marrow edema that extends into the right L4 and L5 pedicles. There is no central stenosis however there is moderate bilateral neural foraminal stenosis.L5/S1:Disc and covering with facet hypertrophy and what appears to be bone graft material. There is no central stenosis however there is mild bilateral neural foraminal stenosis.
