The scanogram shows veiling of the right maxillary and sphenoid sinuses. There is an undisplaced fracture line through the right temporal bones. The sellar and sutures are within normal limits. 

Serial axial and reconstructed images were obtained at 2-5mm slice thickness from the neck to the vertex. They confirmed undisplaced linear fracture on the right temporo-parietal bones (including the mastoid air cells). There is associated hyper dense hematoma collection in the ipsilateral mastoid, right sphenoid, both maxillary and ethmoidal sinuses. The remaining para nasal sinuses appeared normal; except for mucosal thickening in the right maxillary antrum.
Higher cuts showed extensive hypodense collection of air attenuation, occupying the fronto-parietal regions (separating the brain from the inner skull table). Extension was also noted in inter hemispheric fissure and extra axial fluid spaces. Nevertheless, no evidence of mass lesion or fluid collection in the cerebral or cerebellar hemispheres.
A part from subtle effacement, the ventricles appeared normal.
CONCLUSION: Features are those of right temporal skull fracture with intra cranial aerocele and sinus hematoma
