Choristoma of the vestibular nerve: Should it influence our management of vestibular Schwannoma- Case report and review of the literature

Background and Importance: Choristomas of the internal auditory canal and cerebellopontine angle are rare, non-neoplastic lesions that mimic vestibular schwannomas and may subsequently be subject to treatment by surgical resection or radiosurgery. Their management is conservative with observation. Surgical intervention has been associated with expected hearing loss that is counter to the goal of surgery. On the other hand, radiosurgery is not indicated in such pathology and will also lead to eventual hearing loss.
