Vestibular schwannoma mri

Acoustic neuroma is a rare noncancerous tumor. It grows slowly from an overproduction of Schwann cells and is also called a vestibular schwannoma. The tumor then presses on the hearing and balance nerves in the inner ear. Schwann cells normally wrap around and support nerve fibers. A large tumor can press on the facial nerve or brain structures. Vestibular schwannomas, also known as acoustic neuromas, are relatively common tumours that arise from the vestibulocochlear nerve (CN VIII) and represent ~80% of cerebellopontine angle (CPA) masses.

Overall, there is no clear evidence that environmental factors, such as cell phones, cause these tumors. The rising incidence of vestibular schwannomas likely relates to improvements in magnetic resonance imaging (MRI) and increased screening for concerning symptoms. 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.

Magnetic resonance imaging (MRI) is the diagnostic gold standard in vestibular schwannoma. Sensitivity and specificity are both close to 100%. MRI detects the tumour and describes its extension, thereby giving the potential surgeon prognostic clues. Prediction of tumour growth, however, is not possible.

2007 Nov 27; Vestibular schwannoma is a benign tumour of glial cell origin. It most commonly arises from the vestibular branch of the 8 th cranial nerve.

On imaging, they classically present as a solid nodular mass with an intracanalicular component that often results in widening of the porus acusticus.

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
