Acoustic neuromas, also known as vestibular schwannomas, are benign brain tumors that typically grow slowly over many years. These tumors develop on the nerve responsible for hearing and balance, leading to symptoms such as hearing loss and unsteadiness. While acoustic neuromas can sometimes become serious if they grow very large, most are detected and treated before reaching this stage.

Acoustic neuromas can affect anyone, but they are most common in individuals aged 30 to 60. Although their exact cause is often unknown, a small number of cases are linked to a genetic condition called neurofibromatosis type 2.

Symptoms of acoustic neuromas often develop gradually due to the slow-growing nature of these tumors. The primary symptom to watch for is hearing loss in one ear, known as unilateral hearing loss. Other common symptoms include tinnitus (a ringing sound in the ear) and vertigo (a sensation of the room spinning). Larger acoustic neuromas can cause additional symptoms such as severe headaches, temporary blurred or double vision, numbness or weakness on one side of the face, problems with limb coordination (ataxia), and difficulties with swallowing or speaking.

If a doctor suspects an acoustic neuroma, they will refer the patient for further investigations, which typically include hearing tests and brain imaging. The choice of imaging modality—MRI (magnetic resonance imaging) or CT (computed tomography)—depends on availability and the clinician's assessment. MRI scans are particularly useful for identifying acoustic neuromas, which often appear at the cerebellopontine angle of the brain.

Treatment options for acoustic neuromas vary based on the size and position of the tumor, its growth rate, and the patient's overall health. Small tumors may only require monitoring with regular MRI scans, while larger or faster-growing tumors may necessitate active treatment. Surgery is a common treatment option, with the goal of removing as much of the tumor as possible. In cases where complete removal is not feasible, precise beams of radiation can be used to prevent further growth.

Both surgery and radiosurgery carry risks, including facial numbness or paralysis. Therefore, the choice of treatment must be tailored to each individual's circumstances and discussed thoroughly with their healthcare provider.

The prognosis for acoustic neuromas is generally positive, as most tumors grow slowly or not at all. However, large tumors can cause serious complications, such as hydrocephalus (a life-threatening buildup of fluid in the brain). Even with treatment, some symptoms like hearing loss and tinnitus may persist, impacting the individual's ability to work, communicate, and drive. These issues may require additional treatment.

It's important to note that acoustic neuromas can occasionally recur after treatment, with around 1 in 20 people experiencing a recurrence after surgical removal. Regular MRI scans are essential for monitoring and detecting any regrowth.
