An axial, non-contrast enhanced view of the brain shows severe diffuse cerebral and cerebellar edema.Notes: The normal definition between gray and white matter tissue is poor because of the edema. The quadrigeminal and ambient basal cisterns (white arrows) are no longer seen due to upward transtentorial herniation. The fourth ventricle (black circle) is not seen as edematous cerebellum displaces the CSF. The cystic (asterisk) and calcified suprasellar mass is seen.
