ACOUSTIC NEURILEMOMAS Meaning and
Definition
-
Acoustic neuromas, also known as vestibular schwannomas, are benign tumors that develop in the vestibular (balance) nerve. They are typically slow-growing and arise from Schwann cells, which produce the protective covering (myelin) around nerves.
Acoustic neuromas specifically affect the eighth cranial nerve, also known as the vestibulocochlear nerve or acoustic nerve. This nerve is responsible for transmitting both auditory information from the ear to the brain and balance cues from the inner ear. As the tumor grows, it can compress nearby structures, leading to symptoms such as hearing loss, tinnitus (ringing in the ears), dizziness, and problems with balance.
The exact cause of acoustic neuromas is unknown, although there are certain conditions that have been associated with an increased risk, such as neurofibromatosis type 2 (a genetic disorder). Most acoustic neuromas occur spontaneously and are not inherited.
Diagnosis of acoustic neuromas typically involves a combination of medical history assessment, physical examination, and imaging tests such as magnetic resonance imaging (MRI). Treatment options include regular monitoring (watchful waiting approach), surgical removal, and radiation therapy, depending on the size, location, and rate of tumor growth, as well as the overall health of the patient.
Overall, acoustic neurinomas are relatively rare, representing around 8% of all brain tumors. Early detection and appropriate management can lead to better outcomes and improved quality of life for individuals with this condition.

Etymology of ACOUSTIC NEURILEMOMAS
The term "acoustic neuroma" is derived from the Greek words "akoustikos", meaning "pertaining to hearing", and "neuron", meaning "nerve". "Neurilemoma" is composed of the Greek roots "neuri-", meaning "nerve", and "-lemma", referring to a sheath or covering.
Therefore, "acoustic neurilemomas" originates from the Greek words that describe a benign tumor that affects the nerve responsible for hearing and originates from the sheath or covering of the nerve.
