Sensorineural hearing loss and cerebellopontine angle lesions. Not always an acoustic neuroma--a pictorial essay.
Review
Overview
abstract
While an acoustic neuroma is the most common cause of a cerebellopontine angle (CPA) mass, it accounts for only 1-10% of cases of sensorineural hearing loss (SNHL). There are many other etiologies of SNHL, with characteristic imaging features, which may or may not be confined to the CPA.
