tumour, haematoma) may cause herniation of brain tissue through the tentorium into the subtentorial space, putting pressure on the midbrain.
Thereafter, the falx is inspected and removed, followed by the left cerebral hemisphere, such that the whole tentorium is now exposed and can be inspected while intact for tears and hemorrhages.
They are associated with aging and can be seen in the basal ganglia, pineal gland, falx, tentorium, arachnoid granulations, choroid plexus and the cerebellum.
Two layers of meninges (the dura mater and pia mater) covering the brain, the outer one involved in the formation of the tentorium cerebelli, and lining the intracranial venous sinuses.
On contrast-enhanced CT there is diffuse enhancement of the basal subarachnoid cisterns and occasionally of the tentorium and sylvian fissures, but contrast-enhanced MRI is more sensitive in detecting leptomeningeal enhancement [28].
The tentorium was layered with a bilateral hematoma, and bilateral subarachnoid hemorrhage over the parietal and temporal regions was found, which was consistent with a coup/contrecoup injury.

The particular emphasis of the cranial work was on the following locations: where those cranial nerves cross the borders of tentorium cerebelli, as they pass through cavernous sinus, where the particularly vulnerable spot was, the fibro-osseous canal beneath the posterior clinoid processes, at sutura petrobasilaris, and where those nerves enter the orbit through fissure orbital is superior.
The posterior fossa is small and the tentorium is low lying, resulting in crowding of the cerebellum and brainstem into the cervical medullary junction and upper cervical spinal canal.
