A schwannoma (or neurilemmoma) of the jugular foramen is a rare tumour of the head and neck region arising from the cranial nerve sheaths and/or the sympathetic chain. Due to its location, in the early stages of growth there is usually a lack of symptoms. Furthermore, it tends to grow...
“Schwan-nnoma”.Schwannoma or neurilemmoma is a benign (non-cancer) tumor of the covering of the nerves, called nerve sheaths. As the name (neurilemmoma) suggests, the tumor grows along the length of a nerve anywhere in the body, commonly affecting the nerves in the brain and neck. ...
In some cases, they grow into the bones of your head and face, which my change the shape of your skull and face. Schwannomas These may also be called vestibular schwannomas (pronounced shwuh-now-muhs), neurilemmomas (pronounced nyoor-uh-lem-oh-muhs), or acoustic neuromas (pronounced ...
Nearly half of these tumors were neuroblastoma followed by soft tissue sarcoma, Langerhans cell histocytosis, and lymphoma. Ozawa et al. [ 2 ] reported similar findings in a retrospective series of spinal dumbbell tumors, of which nearly 90% accounted for neurogenic origin (mainly schwannomas, ...

An association between thyroid disease andotologicalsymptoms also exists. Vertigo and hearing loss have been described in the setting of hypothyroidism.67Pendred's syndromeis characterized by congenital hearing loss, reduced vestibular responses, and goiter. In a study of 42 kindreds, resistance to ...

The most common primary brain tumors are gliomas (for example, astrocytoma). Meningiomas (meningeal or meninx tumors), pituitary adenomas, craniopharyngiomas, vestibular schwannomas, primaryCNSlymphomas, and primitive neuroectodermal tumors (medulloblastomas) are also primary brain tumors. The termgliomais...
Schwannomas of head and neck regioncommonly arise from the vestibular and vagus nerve. Hypoglossal nerve schwannomas are very rare. They may be intracranial only or have both intra and extracranial extension. Radiology specially, computed tomography (CT) and magnetic resonance (MRI) are useful in ...
