Acoustic Neuroma

Diagnosis

Magnetic resonance imaging (MRI) is the preferred diagnostic test for identifying acoustic neuromas.

Other tests used to diagnose acoustic neuroma and to differentiate it from other causes of dizziness or vertigo include:

• Computed tomography (CT) scan of the head
• Audiology (a test for hearing)
• Caloric stimulation (a test for vertigo)
• Electronystagmography (a test of equilibrium and balance)
• Brain stem auditory evoked response (BAER, a test of hearing and brain stem function)
