It is the most frequent benign tumor found at cerebello-pontine angle. Symptoms usually one sided hearing loss which patients will suffer from ear ringing (tinnitus), dizziness, nystagmus (rapid eye movement) and vertigo, including feel pain in jaw area. A retrospective review on the incidence of acoustic neuroma by Philip R et al. (2009), out of 27 cases conducted in PPUM from 2001 till 2006, 74.1% were above the age of 50 years, while mean age was 56.4 years old. In clinical settings, there are many examinations requested to study this disease. Therefore, this appraisal is definitely to identify the best imaging modalities in acoustic neuroma.
