Findings:
The images are slightly compromised secondary to motion artifact.
There are extensive, symmetric supratentorial and infratentorial foci of hypointensities. These mainly occur at the gray-white junction, the corpus callosum, and the cerebellum.
There is FLAIR hyperintensity within these areas, particularly in the left parietal lobe.
There is leptomeningeal hemosiderin staining in the upper cervical spine and brainstem.
There is mild cerebral edema.
There is mucosal thickening involving the bilateral maxillary sinuses and sphenoid sinuses. There is an effusion in the mastoid air cells.
Extracranially, there is a nodular T2 hyperintense lesion measuring 1.6cm in the right inferior temporal fossa lateral to the medial pterygoid muscle.
There is mild edema present within the suboccipital region at C2-C3 posterior paraspinal soft tissues likely due to interspinous ligament sprain.
There is a small amount of epidural edema in the left ventral aspect at the level of the foramen magnum. There is a C7 transverse process fracture that is better visualized on the admission CT.

Impression:
Findings consistent with diffuse axonal injury. There is mild soft tissue edema in the C2-C3 posterior paraspinal soft tissues likely representing ligamentous sprain. There is also a lesion in the right inferior temporal fossa which may represent an incidental schwannoma.
