Acoustic Neuromas: Symptoms and Diagnosis - Barrow …
Acoustic neuromas are the most common cerebellopontine angle tumor in adults. While their natural history is not fully understood, a subset of tumors demonstrates significant growth over time, necessitating treatment. Clinical manifestations include hearing loss, tinnitus, vertigo, dysequilibrium, and cranial nerve neuropathies.

2023年8月17日 · Acoustic neuromas are commonly located in the cerebellopontine angle, near the cochlear and vestibular nerves, particularly the inferior division of the vestibular nerve. About 5% to 10% of tumors in the cerebellopontine angle (CPA) are meningiomas, which may occur elsewhere in the brain.
Acoustic neuromas can also be called cerebellopontine angle tumors, as well as vestibular or acoustic schwannomas. The vestibular (balance) nerve runs from the inner ear to the brain. An acoustic neuroma is a benign tumor that slowly grows on this nerve. Most of the time, the tumor occurs in only one ear.
