Although stereotactic radiosurgery was considered, we elected against this approach due to the poorer tumor control in NF2-associated vestibular schwannomata as compared to sporadic tumors, the small but nonetheless present risk of malignant transformation of the VS in a patient with a tumor predisposition syndrome, and the suggestion in the literature of poorer hearing outcomes associated with CI implantation in the setting of an irradiated VS.2–4. This evidence concerns the gene NF2 and neoplasm.
