Male, 88 years old, with history of central cord syndrome at C4, prior cervical fusion, evaluate decompression. Findings are seen compatible with laminectomy from spinal canal decompression from C3 through C6. Posterior fusion instruments are also in place from C2 down to T3.The spinal canal is well decompressed through the operative region with relief of multilevel stenoses seen on the prior examination. Patchy cord T2 signal at the C4-5 level is seen which, in the absence of cord swelling, likely represents myelomalacia. The spinal cord otherwise demonstrates normal signal and caliber.Straightening of the cervical lordosis may be related to fixation. Minimal grade 1 anterolisthesis of C7 relative to T1 is unchanged. Vertebral body heights are preserved. Marrow signal characteristics are heterogeneous but there are no areas of concerning marrow replacement. STIR hyperintense signal within the C6-7 disc space is less conspicuous than on the prior examination. Prevertebral soft tissue signal abnormality seen on the prior examination is no longer clearly identified.C2-3: No significant spinal canal or foraminal stenosis. C3-4: Posterior disc-osteophyte complex formation. Posterior spinal canal decompression. Moderate right and mild left foraminal narrowing. C4-5: Posterior disc-osteophyte complex formation. Posterior spinal canal decompression. Moderate bilateral foraminal narrowing.C5-6: Posterior disc-osteophyte complex formation. Posterior spinal canal decompression. Moderate bilateral foraminal narrowing. C6-7: Posterior disc-osteophyte complex formation. Posterior spinal canal decompression. Moderate bilateral foraminal narrowing. C7-T1: No significant spinal canal or foraminal stenosis.
Findings are redemonstrated compatible with spinal canal decompression and posterior instrumented fusion. The canal is expanded through the surgical region with relief of multilevel stenoses seen on the preoperative study.Patchy signal abnormality within the spinal cord at the C4-5 level likely represents myelomalacia. No other spinal cord abnormalities are seen.Signal abnormality within the C6-7 disc and along the anterior prevertebral soft tissues at this level has improved which may represent healing of the previously suspected hyperextension injury.
