Other Diagnostic Studies

Audiogram

Once the symptoms appear, a thorough ear examination and hearing test (audiogram) are essential for proper diagnosis.

CT

Computerized tomography (CT) scans, enhanced with intravenous dye (contrast), and magnetic resonance imaging (MRI) are critical in the early detection of a vestibular schwannoma and are helpful in determining the location and size of a tumor and in planning its microsurgical removal.

Surgery

Schwannomas can be removed surgically, but they can then recur.
