Bilateral acoustic schwannoma is a rare condition characterized by the development of tumors on both acoustic nerves, which connect the inner ear to the brain. Synonyms for this condition include neurofibromatosis type II (NF2), vestibular schwannoma, and bilateral eighth nerve tumors. NF2 refers to the genetic disorder that predisposes individuals to developing multiple tumors, including bilateral acoustic schwannomas. Vestibular schwannoma is a more general term for tumors on the acoustic nerve, while bilateral eighth nerve tumors emphasizes the location of the tumors. Regardless of the terminology used, bilateral acoustic schwannoma can lead to hearing loss, balance problems, and other neurological symptoms.
