Nonacoustic Lesions of the Cerebellopontine Angle T2 CURRENT Diagnosis & Treatment in Otolaryngology—Head & Neck Surgery, 3e YR 2012 FD 2012 PB The McGraw-Hill Companies PP New York, NY SN 978-0-07-162439-8 LK accessmedicine.mhmedical.com/content.aspx?aid=55772631 RD 2024/04/19 AB Vestibular schwannomas (acoustic neuromas) account for 80% of all lesions of the cerebellopontine angle (CPA). This chapter discusses some of the other common neoplasms (meningiomas and epidermoid cysts) as well as uncommon tumors of the CPA that commonly present with injury to the cochlear–vestibular system. Each of these tumors has a similar clinical presentation; they are primarily differentiated by their imaging characteristics.
