 There are postoperative findings related to posterior fusion of C3-C6 with bilateral pedicular screws and laminectomies at the levels, new from prior exam. Hardware related susceptibility artifact limits evaluation of these levels. The spinal canal at the postoperative levels shows no significant canal stenosis. Abnormal T2 hyperintense signal abnormality in the cervical cord has significantly decreased from prior exam although persistent at the C3-4 level with mild focal cord expansion and mild enhancement within the cord. There is disk desiccation and loss of disk height at multiple levels in the cervical spine. Vertebral body heights are preserved. The osseous marrow signal is benign.There is ill-defined enhancement of the posterior paraspinal and subcutaneous soft tissues which is likely postsurgical. No definite pathologic enhancement is identified elsewhere.C2-3: No disk herniation or spinal stenosis.C3-4: Postsurgical changes, small disk osteophyte complex with no spinal stenosis. However, there is mild residual effacement of the right lateral aspect of the thecal sac still present without significant spinal stenosis. Hyperintense T2 cord signal abnormality and focal cord expansion with mild enhancement as described above.C4-5: Postsurgical changes, disk osteophyte complex with no spinal stenosis.C5-6: Postsurgical changes, disk osteophyte complex with no spinal stenosis.C6-7: Posterior changes, disk osteophyte complex with uncovertebral hypertrophy causing mild right neural foraminal stenosis.C7-T1: No disk herniation or spinal stenosis.T1-2: No disk herniation or spinal stenosis.T2-3 and T2-4 levels show no disk herniation or spinal stenosis on the sagittal images.
Postoperative findings related to posterior fusion of C3-C6 and decompressive laminectomies with spinal canal stenosis no longer seen at the postoperative levels. Marked interval decrease in abnormal T2 cord signal with persistent signal abnormality and focal expansion of the cord at C3-4.
