61-year-old male with a right deltoid weakness after anterior C4 corpectomy and fusion of C3-C5, posterior cervical laminectomy of C3-C6, and posterior C2-T2 fusion. Postoperative findings compatible with C4 corpectomy and graft placement with C3-C5 anterior fusion, as well as posterior C2-T2 fusion with lateral mass screws at C2-C6 and pedicle screws that T1-T2. There is thickening and T2 hyperintensity of the retropharyngeal/prevertebral space consistent with possible postsurgical changes of the anterior approach. There is some signal abnormality and myelomalacia between C4 and the superior portion of C5 that likely represents sequelae of prior compression. Craniovertebral junction appears within normal limits. Bone marrow signal is within normal limits. There are severe spondylotic changes visualized within the cervical spine including diffuse loss of disc height worst at C7-T1, diffuse disc desiccation, and compression deformities worst at C3 and C5. There is diffuse uncovertebral hypertrophy. These cause diffuse neuroforaminal narrowing worst at the right greater than left neural foramen at C4-C5 and C5-C6. The vertebral artery flow voids appear to be intact. Paraspinous soft tissue structures appear within normal limits.
1. Postoperative findings from C4 corpectomy, anterior fusion of C3-C5, laminectomy of C3-C7, and fusion of C2-T2.2. Multilevel spondylosis is visualized consistent with prior examinations. Significant bilateral neural foraminal stenosis from uncovertebral hypertrophy is visualized and is worst at C4-C5 and C5-C6.
