Acoustic neuromas have been shown to grow more slowly, if at all, in the elderly. Reduction of tumor size has been rarely reported in intracranial masses thought to be acoustic neuromas. We present a biopsy-proven acoustic neuroma that involuted completely during a 4-year period of surveillance. Possible mechanisms of involution are discussed.
