posterior cranial fossa

Lies in the anterior wall of the posterior cranial fossa.

About 60% will be in the posterior cranial fossa (particularly the cerebellum).

The posterior cranial fossa is formed in the endocranium, and holds the most basal parts of the brain.

The tumor destroys the mastoid air spaces and extends into the middle ear and/or posterior cranial fossa.

Arachnoiditis of posterior cranial fossa (blindness, deafness, hemiplegia).

Groove for Sigmoid Sinus is a groove in the posterior cranial fossa.

They also occur in the posterior cranial fossa, and near the falx cerebri and tentorium cerebelli.

Walter Dandy in 1925 was an advocate of partial sectioning of the nerve in the posterior cranial fossa.

The intermediate nerve reaches the posterior cranial fossa via the internal acoustic meatus before synapsing in the solitary nucleus.

Posterior cranial fossa (fossa cranii posterior )

The posterior cranial fossa is part of the intracranial cavity, located between the foramen magnum and tentorium cerebelli.

The vertebral artery supplies a number of vital structures in the posterior cranial fossa, such as the brainstem, the cerebellum and the occipital lobes.

Pediatric ependymomas most often occur in the posterior cranial fossa, in contrast with adult ependymomas which usually occur along the spine.

"The doc's term for it was, 'Blunt-force trauma to the posterior cranial fossa, resulting in cerebellar herniation and damage to the midbrain.'

Neuroradiological diagnosistics evaluate the severity of crowding of the neural structures within the posterior cranial fossa and their impact on the foramen magnum.

Also visible in the posterior cranial fossa are depressions caused by the venous sinuses returning blood from the brain to the venous circulation:

In the case of epidural hematoma in the posterior cranial fossa, the herniation is tonsillar and causes the Cushing's triad: hypertension, bradycardia, and irregular respiration.

A brain CT scan revealed lesions in the cerebral hemispheres and posterior cranial fossa due to a cerebellar metastatic tumor which consequently led to compression of the midbrain.

The cerebellar falx (or falx cerebelli) is a vertical dural infolding that lies inferior to the cerebellar tentorium in the posterior part of the posterior cranial fossa.

It has also reported that the presence of a Cushing reflex due to an ICP increase could allow one to conclude that ischemia has occurred in the posterior cranial fossa.

Primary (true) brain tumors are commonly located in the posterior cranial fossa in children and in the anterior two-thirds of the cerebral hemispheres in adults, although they can affect any part of the brain.

The larger anterior space includes the anterior and middle cranial fossas and lodges the cerebrum; the small posterior space- the posterior cranial fossa contains the cerebellum, the pons, and the medulla.

Other areas more susceptible to fractures are the cribriform plate, the roof of orbits in the anterior cranial fossa, and the areas between the mastoid and dural sinuses in the posterior cranial fossa.

The hiatus for lesser petrosal nerve receives the lesser petrosal nerve as it branches from the glossopharyngeal nerve (CN IX) before the glossopharyngeal enters the posterior cranial fossa through the jugular foramen.
