Abstract
The cerebellopontine angle (CPA) is a triangular subarachnoid space located within the posterior cranial fossa and centered at the level of the internal audiotary canal. CPA masses represent about 10% of intra cranial tumours and 80% of these are vestibular schwannomas and the remaining 20%are meningiomas and other masses.
