[Acoustic neurinoma shown as a facial palsy].

Acoustic neurinoma is the most frequent benign tumour at the cerebellopontile angle. It causes compressive type lesions in adjacent cerebral structures. Its usual symptoms are sensorineural hearing loss and tinnitus with or without unilateral vertigo, which is why we have to know the wide variety of clinical signs it can present from its beginning, including facial palsy. We present the case of a vestibular schwannoma in a pregnant lady diagnosed by a peripheral facial palsy.
