It usually is found in the cerebrum or cerebellopontine angle.

The cerebellopontine angle is a space filled with spinal fluid.

Moreover, it could cause an infarct of the cerebellopontine angle.

The translabyrinthine approach is the most versatile of the 3 common approaches to the cerebellopontine angle.

The cerebellopontine angle is a structure at the margin of the cerebellum and pons.

From its origin, it branches along the inferior portion of the pons at the cerebellopontine angle before reaching the cerebellum.

It is used in the surgical extirpation of lesions of the cerebellopontine angle, including acoustic neuroma.

The translabyrinthine approach is a surgical approach to the cerebellopontine angle, or CPA.

Puusepp performed the first brain tumor operation in Estonia on April 30, 1921, for a right-sided cerebellopontine angle mass.

Bruns nystagmus is an unusual type of bilateral nystagmus most commonly occurring in patients with cerebellopontine angle tumours.

Some surgeons extend the use of the middle fossa technique to include tumors that extend as much as 0.5-1.0 cm into the cerebellopontine angle.

The inferior portions of the cerebellopontine angle and cranial nerves are not as well visualized as they are in the retrosigmoid approach.

A distinct neurologic syndrome of deficits occurs due to the anatomic proximity of the cerebellopontine angle to specific cranial nerves.

As the tumor grows, it usually extends into the posterior fossa to occupy the angle between the cerebellum and the pons (cerebellopontine angle).

Cerebellopontine cistern (Angle cistern or cerebellopontine angle cistern).

The two lateral apertures provide a conduit for cerebrospinal fluid to flow from the brain's ventricular system into the subarachnoid space; specifically into the cerebellopontine angle.

Contrast-enhanced CT will detect almost all acoustic neuromas that are greater than 2.0 cm in diameter and project further than 1.5 cm into the cerebellopontine angle.

Further causes, besides an aneurysm, multiple sclerosis or cerebellopontine angle tumor, include: a posterior fossa tumor, any other expanding lesion or even brainstem diseases from strokes.

The inferior portions of the cerebellopontine angle and the posterior surface of the temporal bone anterior to the porus acusticus are much more clearly observed than via the translabyrinthine approach.

The two other openings of the fourth ventricle are lateral apertures (foramina of Luschka), one on the left and one on the right, which drain cerebrospinal fluid into the cerebellopontine angle cistern.

He also did the first operation for complete removal of a cerebellopontine angle tumor, as well as being one of the first surgeons to perform a radical mastoidectomy with ligation of the jugular vein.

Cha ST, Mathiasen RA, Jarrahy R, Suh R, Shahinian HK: Cerebellopontine angle metastasis from papillary carcinoma of the thyroid: case report and literature review.

Lesions in the area of cerebellopontine angle cause signs and symptoms secondary to compression of nearby cranial nerves, including cranial nerve V, cranial nerve VII, and cranial nerve VIII.

Although some surgeons use an extended middle cranial fossa approach for tumors that extend a centimeter or more outside the porus acusticus into the cerebellopontine angle, the middle cranial fossa approach is most frequently used for intracanalicular tumors.

They involved the cranial nerves inside the so-called cerebellopontine angle, "a very small place on the underside of the brain," as Mr. Shelton puts it in "Working in a Very Small Place," subtitled "The Making of a Neurosurgeon."
