Status post trauma, no neurologic activity. Normal gray-white matter differentiation. There are no changes to suggest diffuse axonal injury however MRI would be more sensitive in detecting changes of DAI. No coup or contra-coup lesion demonstrated.There is no evidence of acute intracranial hemorrhage, mass, midline shift or edema. No intra or extra-axial collection. There is a 5 mm thick left scalp hematoma overlying the left parietal-temporal region.The ventricles and basal cisterns are normal in size and configuration.The calvaria and skull base are radiographically normal. No fracture or diastases demonstrated.Mucosal thickening is seen in maxillary antrum with a fluid level on the right and in the sphenoid sinuses. Nonspecific soft tissue opacification seen in the right ethmoid cells. The remainder of the visualized paranasal sinuses and mastoid air cells are normally pneumatized.
*Normal unenhanced brain CT.*No acute intracranial abnormality. However MRI would be more sensitive in detecting changes of DAI.
