Transcalvarial herniation is the extrusion of cerebral tissue through the cranium.In the presence of severe cerebral edema,transcalvarial herniation occurs through an opening from a skull fracture or craniotomy site.These effects are indicative of central herniation from an expanding mass lesion of the midline,frontal,parietal,or occipital lobes.In uncal herniation,a unilateral,expanding mass lesion,usually of the temporal lobe,increases intracranial pressure,causing lateral displacement of the tip of the temporal lobe (uncus).Cingulate herniation occurs when an expanding lesion of one hemisphere shifts laterally and forces the cingulate gyrus under the falx cerebri.
