Lesions in the area of cerebellopontine angle cause signs and symptoms secondary to compression of nearby cranial nerves, including cranial nerve V (trigeminal), cranial nerve VII (facial), and cranial nerve VIII (vestibulocochlear). The most common cerebellopontine angle (CPA) tumor is a vestibular schwannoma affecting cranial nerve VIII (80% ...
The cerebellopontine angle (CPA) (Latin: angulus cerebellopontinus) is located between the cerebellum and the pons. [1] The cerebellopontine angle is the site of the cerebellopontine angle cistern. [2] The cerebellopontine angle is also the site of a set of neurological disorders known as the cerebellopontine angle syndrome.
Thus Koos grade 1 is a purely intrameatal (IAC) tumor, 1–10 mm in size; Koos grade 2, 10–20 mm, has extended into the cerebellopontine angle (CPA), but with no brainstem contact; Koos grade 3, 20–30 mm, fills the CPA space and touches on the brainstem, but without compression; and Koos grade 4, more than 30 mm in size, compresses the ...
Bruns nystagmus is an unusual type of bilateral nystagmus most commonly occurring in patients with cerebellopontine angle tumours.It is caused by the combination of slow, large amplitude nystagmus (gaze paretic nystagmus) when looking towards the side of the lesion, and rapid, small amplitude nystagmus (vestibular nystagmus) when looking away from the side of the lesion.

The condition, which occurs due to a portion of the skull being misshapen or too small, can cause symptoms like headaches, dizziness and vertigo, weak muscles, difficulty with balance or ...
Epidermoid tumors strongly adhere to the brain stem or cranial nerves. Often the lining of the tumor connected to the brain stem or parts difficult to "peel" away are left behind leaving residual tumor after surgery, this can contribute to the risk of regrowth. About 40% of these cysts originate in the cerebellopontine angle. [3]
