Anterior cervical discectomy and fusion changes from C6 to T1 with C7 corpectomy, as well as posterior spinal fixation changes from C4 to T2.
There is diffusely abnormal, expansile intramedullary heterogeneous T2 signal extending from the cervical medullary junction inferiorly throughout the cervical and visualized thoracic spinal cord. Some areas have corresponding subtle intrinsic T1 hyperintensity and susceptibility artifact, likely representing blood products. Posterior to the C6 and C7 vertebral bodies, there is a relatively more homogeneous T2 signal, without significant visible spinal cord parenchymal signal, concerning for transection.
The multiple osseous spinal fractures were better visualized on the prior CT. There is significant paravertebral edema and disruption of the posterior tension band from C6 to approximately T1.
