  2. Vestibular schwannoma - Wikipedia

    en.wikipedia.org/wiki/Vestibular_schwannoma

    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.

  3. Schwannoma - Wikipedia

    en.wikipedia.org/wiki/Schwannoma

    Schwannomas of the head and neck are a fairly common occurrence and can be found incidentally in 3–4% of patients at autopsy. [4] Most common of these is a vestibular schwannoma, a tumor of the vestibulocochlear nerve that may lead to tinnitus and hearing loss on the affected side. Outside the cranial nerves, schwannomas may present on the ...

    en.wikipedia.org/wiki/Neurofibromatosis_type_II

    The types of tumors frequently associated with NF2 include vestibular schwannomas, meningiomas, and ependymomas. The main manifestation of the condition is the development of bilateral benign brain tumors in the nerve sheath of the cranial nerve VIII , which is the "auditory-vestibular nerve" that transmits sensory information from the inner ...

  5. Schwannomatosis - Wikipedia

    en.wikipedia.org/wiki/Schwannomatosis

    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 ...

  6. Cerebellopontine angle syndrome - Wikipedia

    en.wikipedia.org/wiki/Cerebellopontine_angle...

    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

  7. Nervous system tumor - Wikipedia

    en.wikipedia.org/wiki/Nervous_system_tumor

    A nervous system tumor is a tumor that arises within the nervous system, either the central nervous system (CNS) or the peripheral nervous system (PNS). [1] [2] Nervous system primary tumors include various types of brain tumor and spinal tumors, such as gliomas, and meningiomas (of the CNS), and schwannomas (of the PNS) and can be either benign or malignant.

  8. Cerebellopontine angle - Wikipedia

    en.wikipedia.org/wiki/Cerebellopontine_angle

    Tumours can arise in the cerebellopontine angle. Four out of five of these tumours are vestibular schwannomas (commonly known as acoustic neuromas). [3] Others found include: Arachnoid cyst; Facial nerve tumour; Lipoma; Meningioma; Schwannoma of other cranial nerves (e.g. CN V >VII>IX, X, XI) Metastasis; Intracranial epidermoid cyst

  9. Central Brain Tumor Registry of the United States - Wikipedia

    en.wikipedia.org/wiki/Central_Brain_Tumor...

    A vestibular schwannoma (VS) is only one type of tumor. The Central Brain Tumor Registry of the United States (CBTRUS) is the primary national database of malignant and benign tumors of the brain, "other central nervous system (CNS), tumors of the pituitary and pineal glands, olfactory tumors of the nasal cavity, and brain lymphoma and leukemia."
