An acoustic neuroma (AN) is a rare benign brain tumour, which is also known as acoustic neuroma, vestibular schwannoma and cerebellopontine angle tumour. As it is a benign tumour, it does not allow secondary growth (does not spread to other parts of the body). It does not become malignant (cancerous) and usually, grows very slowly. If you have a tumour in the brain, where it shouldn’t belong, the details of the same may not be comforting.
How long does Acoustic Neuroma Last?
- The tumour grows slowly and the symptoms vary depending on the size and location of the tumour. If the tumour goes undetected and untreated, it can give rise to several problems with hearing, balancing of posture and life-threatening medical conditions over a period of time (short or long term).
- In many people, the acoustic neuroma may be small, asymptomatic and grow very slowly. If the tumour is small with few or no symptoms, especially in older patients (more than 65 years), it can be observed over a period of time until further symptoms develop. During the observation period, your doctor may recommend periodic MRIs to monitor the progress of the tumour. If no significant increase in the size or symptoms occurs, observation may be continued. If the tumour shows rapid growth, the treatment becomes necessary. Observation is usually not preferred in younger patients due to the risk of increase in hearing loss if the tumour is not treated and a further increase in tumour size may make treatment more difficult at a later point in time.
- Hearing loss is a common symptom of acoustic neuroma and is usually permanent. Furthermore, it does not return after the surgery for tumour.
