T2
Dissociation between the T1 and T2 vertebral bodies with presence of a small bone fragment in the right anterior spinal canal deforming and compressing the spinal cord with abnormal signal.Strong evidence of a major CSF leak with almost no CSF visible surrounding the spinal cord. Increased signal in the C1-C2 joint spaces without malalignment. This could represent injury involving those articulations without complete disruption. However, the tectorial membrane is focally disrupted posterior to the dens.
