Acoustic Neuroma and Other Cerebellopontine Angle Tumors: Detecting a Neoplasm in the Cerebellopontine Angle


Acoustic neuromas (ANs) are schwannomas that arise mainly from the vestibular division of the eighth cranial nerve (vestibular nerve) [1]. They constitute 6% of intracranial tumors. In recent years, the incidence of newly diagnosed ANs in Denmark was 13 per million population [2]. ANs are classified into two forms: sporadic and neurofibromatosis type 2 (NF2). Sporadic ANs are usually unilateral, whereas NF2 ANs, which are caused by a mutation of chromosome 22 [3], are usually bilateral.
