What is the difference between acoustic neuroma and vestibular schwannoma?

What is the difference between acoustic neuroma and vestibular schwannoma?

Acoustic neuromas arise from Schwann cells, which wrap around and support nerve fibers, hence the name vestibular schwannoma. Schwannomas can occur on any cranial or peripheral nerve in the body, but in the brain, acoustic neuromas are the most common schwannomas.

How long does it take for acoustic neuroma to grow?

Although most acoustic neuromas grow slowly, some grow quite quickly and can double in volume within 6 months to a year. Although some tumors adhere to one or another of these growth patterns, others appear to alternate between periods of no or slow growth and rapid growth.

What mimics acoustic neuroma?

Meningioma is a rare and typically benign (non-cancerous) tumor that can mimic an acoustic neuroma.

Can stress cause acoustic neuroma?

Stress has been postulated to trigger or contribute to inner ear pathologies but there is little objective evidence. We investigated stress hormones in Ménière’s patients and patients with acoustic neuroma. Data were compared with those from a control group of patients with facial spasm.

What happens if acoustic neuroma is untreated?

Left untreated, an acoustic neuroma can block the flow of cerebrospinal fluid and cause hydrocephalus, which can in turn lead to severe vision problems and difficulty breathing and swallowing. Fortunately, most patients seek treatment long before an acoustic neuroma reaches this stage.

What is the prognosis for acoustic neuroma?

The outlook (prognosis) is generally very good. Acoustic neuromas usually respond well to treatment and complications are uncommon. However, there is often some hearing loss in the affected ear after treatment. Fewer than 5 in every 100 acoustic neuromas come back.

Is acoustic neuroma considered a disability?

An acoustic neuroma is a serious medical condition that may result in disability. To file a successful long term disability claim, you must support your claim with sufficient medical evidence and proof of appropriate treatment.
