Abstract

Bilateral vestibulopathy (BV) is characterized by oscillopsia and imbalance during locomotion. Half of the cases of BV are idiopathic, and BV due to brain tumor has been reported only rarely. We report a case of BV due to bilateral cerebellopontine-angle tumors in a patient with neurofibromatosis type 2. Careful history on oscillopsia and imbalance during locomotion, and regular follow-ups using the head-impulse test and dynamic visual acuity are warranted in patients with neurofibromatosis type 2.
