The growth rate of acoustic neuromas: a report of three cases

Until the present time, only a few CT air-cisternographic studies have been done to define the growth rate of acoustic neuromas. By using this method of study, we were able to observe a slow growth rate fo acoustic neuromas in a 41- and a 50-year-old woman over periods of 6-10 months. In contrast, we were unable to find any increase in tumor size during a period of 22 months in a 70-year-old woman.
