Abstract: The best approach for the acoustic neuroma is the complete removal of tumor in a single procedure, with the maximum preservation of the neurologic functions. However, in some cases the surgical removal is not indicated. The authors present a case of acoustic neuroma which was not surgically managed and with 22 years of follow-up. The radiologic evaluation of the lesion showed no progression of the tumor. Between the symptoms of the patient - hearing loss and tinnitus -, only the first gradually worsened. The behavior of the tumor in this patient, which is uncommon, leads to the necessity of further discussion about the management of the acoustic neuromas.
