title: Schwannoma of the vestibulocochlear nerve presenting as isolated paroxysmal vertigo.
abstract: We report a patient with a schwannoma of the eighth cranial (vestibulocochlear) nerve who presented with isolated episodes of paroxysmal vertigo and positive Dix-Hallpike maneuver, and without the common features of hearing loss, disequilibrium and tinnitus. There are no previous reports of paroxysmal episodes of vertigo as the sole manifestation of schwannoma of the vestibulocochlear nerve. Hence, recurrent paroxysmal vertigo should therefore prompt the physician to rule out schwannoma of the vestibulocochlear nerve as a potential cause even in the presence of normal hearing tests.
