The basion-dens interval is augmented concerning with a craniocervical dissociation with an associated extensive prevertebral hematoma. There is consequent irregular contrast extravasation surrounding the basilar artery in keeping with a transection injury. Related diffuse and thick subarachnoid hemorrhage predominantly in the suprasellar and prepontine cisterns with intraventricular extension can be observed. Additionally, poor grey-white matter differentiation on the basal ganglia regions bilaterally is seen, translating diffuse incipient cerebral edema. Also note diffuse narrowing and subtle irregularity of intracranial arteries in line with secondary cerebral vasoconstriction. Status post intubation, nasopharyngeal tube in situ with small amount of fluid in its distal opening.
