摘要

Intravestibular lipoma (IVL) and intravestibular schwannoma (IVS) are rare tumors occupying the intravestibular space. Patients with IVL or IVS complain of hearing impairment, tinnitus or recurrent rotatory vertigo. Therefore, the clinical practitioner could misdiagnose them as sudden sensorineural hearing loss or Meniere's disease. Since delayed diagnosis and treatment could lead to more severe and refractory symptoms, clinicians should have a high index of suspicion for early diagnosis. Recent advancements in imaging diagnostic tools such as computed tomography and magnetic resonance imaging have facilitated the correct diagnosis of these intravestibular tumors without surgical removal. Presently, we report two different kinds of intravestibular tumors of lipoma and schwannoma which manifest different clinical course and treatment strategies.
