The cerebellopontine angle is the anatomic space between the cerebellum and the pons filled with cerebrospinal fluid.
2.
A distinct neurologic syndrome of deficits occurs due to the anatomic proximity of the cerebellopontine angle to specific cranial nerves.
3.
From its origin, it branches along the inferior portion of the pons at the cerebellopontine angle before reaching the cerebellum.
4.
They tend to occur off the midline, especially in the so-called cerebellopontine angle or in the basal areas above the pituitary gland.
5.
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.
6.
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 pontocerebellar cistern at the cerebellopontine angle.
7.
The "'translabyrinthine approach "'is a surgical approach to the cerebellopontine angle, or CPA . It is used in the surgical extirpation of lesions of the cerebellopontine angle, including acoustic neuroma.

9.
This type of injury may rarely be caused by an aneurysm ( an outpouching of a blood vessel ); by an AVM ( arteriovenous malformation ); by a tumor; such as an arachnoid cyst or meningioma in the cerebellopontine angle; or by a traumatic event such as a car accident.

He described in 1921 an operation for the removal of tumors of the pineal region, in 1922 complete removal of tumors of the cerebellopontine angle ( namely acoustic neuromas ), in 1922 the use of endoscopy for the treatment of hydrocephalus ( " cerebral ventriculoscopy " ), in 1925 sectioning the trigeminal nerve at the brainstem to treat trigeminal neuralgia, in 1928 treatment of M�ni�re's disease ( recurrent vertiginous dizziness ) by sectioning the vestibular nerves, in 1929 removal of a herniated disc in the spine, in 1930 treatment of spasmodic torticollis, in 1933 removal of the entire cerebral hemisphere ( " hemispherectomy " ) for the treatment of malignant tumors, in 1933 removal of deep tumors within the ventricular system, in 1935 treatment of carotid-cavernous fistulas ( CCFs ), in 1938 ligation or " clipping " of an intracranial aneurysm, and in 1941 removal of orbital tumors.
