A vestibular schwannoma (VS), also called acoustic neuroma, is a benign tumor that develops on the vestibulocochlear nerve that passes from the inner ear to the brain. The tumor originates when Schwann cells that form the insulating myelin sheath on the nerve malfunction. Normally, Schwann cells function beneficially to protect the nerves which ...
An acoustic neuroma is a schwannoma on the vestibular nerve in the brain. This nerve is involved in hearing and patients with vestibular schwannomas experience hearing loss. However, bilateral vestibular schwannomas (vestibular schwannomas on both sides of the brain) do not occur in schwannomatosis. Juvenile vestibular tumors do not occur ...
For asymptomatic or incidental schwannomas or neurofibromas, only continued imaging is typically indicated to assess whether tumor growth is occurring. [1] Surgical resection may be an option for tumors causing extensive radicular pain or other symptoms, and for tumors exhibiting aggressive behavior. [ 1 ]
NF2 is a genetically transmitted condition. Diagnosis is most common in early adulthood (20–30 years); however, it can be diagnosed earlier. NF2 can be diagnosed due to the presence of a bilateral vestibular schwannoma, or an acoustic neuroma, which causes a hearing loss that may begin unilaterally. [14]
This surgical approach is typically performed by a team of surgeons, including a neurotologist (an ear, nose, and throat surgeon specializing in skull base surgery) as well as a neurosurgeon. In this approach, the semicircular canals and vestibule , including the utricle and the saccule of the inner ear are removed with a surgical drill ...
The suspect in the New Orleans attack that killed 14 people on New Year's Day is believed to have acted alone in a "premeditated and evil act," the FBI has said. The latest information is counter ...
The most common cerebellopontine angle (CPA) tumor is a vestibular schwannoma affecting cranial nerve VIII (80%), followed by meningioma (10%). The cranial nerves affected are (from most common to least common) : VIII (cochlear component), VIII (vestibular component), V Acoustic neuroma/vestibular schwannoma
A warning has been issued to travelers over the spread of three diseases, including the Marburg virus. It’s a close cousin of Ebola that’s been dubbed the “bleeding eye” virus due to one ...
