Observation of Acoustic Neuromas

Since acoustic neuromas are benign, often slow-growing tumors, careful observation over a period of time may be appropriate for some patients. When a small tumor is discovered in an older patient, observation to study the growth rate of the tumor may be indicated if acute symptoms are not present. A MRI scan of the tumor and surrounding region must be performed periodically to determine if there is any significant change in the size of the tumor. If the tumor does not grow, and if debilitating symptoms do not occur (this is rare), observation is continued. If the tumor increases in size, treatment may be recommended.
