Brief summary
Investigators want to know the natural history of the vestibular schwannomas: increasing, decreasing or stability, by monitoring more than 3 MRIs during a span of more than 2 years. They will obtain 3 groups: the volume increasing schwannomas which will be the most important group, the schwannomas that will be stable and a small group where the schwannomas will decrease. The secondary purpose is that the investigators want to know the threshold values: a minimum volume under which we are sure that the schwannoma will not increase, a maximum value where it will increase and if its evolution can be correlated to clinical or radiological criteria.
