Vestibular schwannomas containing cystic parts are common, but it is extremely rare for a vestibular schwannoma to contain fluid-fluid levels. In this report, we present two cases of vestibular schwannoma with magnetic resonance imaging findings of a fluid-fluid level, and we discuss the radiological features and possible mechanism of fluid-fluid level formation.
