Management of Bevacizumab-Induced Proteinuria Using an Angiotensin Receptor Blocker (ARB) in a Neurofibromatosis Type 2 (NF-2) Patient With Vestibular Schwannoma.

Neurofibromatosis type 2 (NF-2) is a genetic condition that by definition includes bilateral vestibular schwannoma, a non-malignant lesion also known as acoustic neuroma. Patients often develop hearing impairment and hearing loss as a result of the involvement of the vestibulocochlear nerve bilaterally as well as attempts at surgical repair. A common treatment for NF-2-mediated schwannoma is the antiangiogenic agent, bevacizumab.
