What we should know about cerebellopontine angle non-vestibular schwannoma?

Abstract

A patient with pontocerebellar pathology has complaints in the ENT field, like hearing loss, tinnitus, vertigo or facial pain The vestibular and non-vestibular schwannoma are the most frequent pathologies of this anatomical region, and because of their “mild” clinical manifestations, the diagnosis can be delayed during a regular follow-up. Improvement of differential diagnosis between vestibular schwannoma and non-vestibular schwannoma requires a detailed anamnesis as well as radiological and electrophysiological exams. Nevertheless, the non-vestibular tumors are often misdiagnosed as vestibular tumors. The surgeon must have all the knowledge and skills in order to provide, case by case, the right diagnosis and the best care for his patient. The aim of this publication is to overview the most recent data related to pontocerebellar non-vestibular schwannoma.
