Tests and diagnosis

By Mayo Clinic Staff

Because signs and symptoms of acoustic neuroma are likely to develop gradually and because symptoms such as hearing loss can be indicators of other middle and inner ear problems, it may be difficult for your doctor to detect the tumor in its early stages.

After asking questions about your symptoms, your doctor will conduct an ear exam. Your doctor may order the following tests:

  • Hearing test (audiometry). In this test, conducted by a hearing specialist (audiologist), you hear sounds directed to one ear at a time. The audiologist presents a range of sounds of various tones and asks you to indicate each time you hear the sound. Each tone is repeated at faint levels to find out when you can barely hear. The audiologist may also present various words to determine your hearing ability.
  • Scans. Contrasted magnetic resonance imaging (MRI) or computerized tomography (CT) scans of your head can provide images that confirm the presence of an acoustic neuroma.
