Concordance of Bilateral Vestibular Schwannoma Growth and Hearing Changes in Neurofibromatosis 2

Abstract

A significant 1-year change in VS size and hearing occurred in NF2 patients. Clinically, tumor change or hearing deterioration on one VS cannot be used to predict changes in the other VS. This suggests that, although NF2 is a Mendelian disease, the germline genotype-phenotype relationship may resemble that of complex disorders.
