Acoustic neuroma is another term for vestibular schwannoma.

The concept at play is naming a tumor by its tissue of origin and nerve involvement. Acoustic neuroma is the historical or lay term for a tumor that actually arises from Schwann cells of the vestibulocochlear nerve. The correct anatomical name is vestibular schwannoma, since the tumor originates from the vestibular portion of cranial nerve VIII and is a Schwann cell–derived lesion. This distinction matters because it points to the nerve component affected and aligns with medical terminology. In the cerebellopontine angle and often extending into the internal auditory canal, vestibular schwannomas primarily disrupt hearing and balance, causing unilateral sensorineural hearing loss, tinnitus, and vertigo. Other options describe different entities: meningioma comes from the meninges, schwannomatosis refers to a condition with multiple schwannomas rather than this single lesion, and oligodendroglioma arises from oligodendrocytes within the brain parenchyma, not from cranial nerves.
