Recent findings The current gold-standard imaging study for vestibular schwannomas is a gadolinium-enhanced T1-weighted MRI. The yield of this expensive study is only about 3–4% given the low incidence of vestibular schwannomas, thus there is utility in screening with noncontrast T2-weighted MRI, which is a quicker 2018-08-30 2021-04-18 Vestibular schwannoma (VS) is associated with dizziness and vertigo during all stages of treatment. This report describes a patient who presented with a one-year history of intermittent motion sickness, dizziness, headache, imbalance, and nausea. MRI showed a right-side VS in the cerebellopontine angle and internal auditory canal. The patient elected to undergo Gamma Knife radiosurgery for An acoustic neuroma (also known as vestibular schwannoma or acoustic neuroma) is a benign (nonmalignant), usually slow-growing tumor that develops from the balance and hearing nerves supplying the inner ear. The tumor comes from an overproduction of Schwann cells—the cells that normally wrap around nerve fibers to help support and insulate nerves.

Vestibular schwannomas, also known as acoustic neuromas, are relatively common tumors that arise from the vestibulocochlear nerve (CN VIII) and represent ~80% of cerebellopontine angle (CPA) masses. Bilateral vestibular schwannomas are strongly suggestive of neurofibromatosis type 2 (NF2).

– Associated with better post operate gait stability because there is minimal retraction of the cerebellum, lowest incidence of postoperative headaches • Retrolabyrinthine: Vestibular schwannomas (also known as acoustic neuromas) make up about ten percent of primary intracranial tumors. They are benign and tend to grow very slowly off the vestibular nerve as it exits the brainstem and heads into the internal auditory meatus towards the inner ear. This region is known anatomically as the cerebellopontine angle. A benign cerebellopontine angle tumour that grows from the superior vestibular component of the vestibulocochlear nerve, usually presenting with unilateral sensorineural hearing loss.

A common area for schwannomas is the nerve connecting the brain to the inner ear. This type is called a vestibular schwannoma or an acoustic neuroma. Cancerous schwannomas most frequently affect the sciatic nerve of the leg, the brachial plexus nerves in the arm, and the group of nerves in the lower back called the sacral plexus.

Although benign, it represents a threat to intracranial structures due to mass effect and carries a small risk of malignant transformation. VS therefore represents an important healthcare burden.
