Depending on the localization, growth rate and size of the tumors, patients can present with subtle, gradually worsening or abrupt and severe neurological compromise or can be completely asymptomatic. [orpha.net]

This book represents an attempt by the present authors to assemble the pertinent data on individual cases of familial brain tumours published since 1896. [books.google.com]

The variation was not present in healthy controls, and all seven meningiomas analyzed displayed loss of the wild-type allele according to the classic two-hit model for tumor-suppressor genes. [ncbi.nlm.nih.gov]

In addition to skin and neurologic examinations, workup included audiometry, complete ophthalmologic examination with slit-lamp biomicroscopy of the lens and fundus, and gadolinium-enhanced MRI of the brain and, in some, of the spine. [muse-meson.com]

Although much more is now known about the classification, prognosis, and treatment of these tumours, and a number of familial cases have been reported, the present data are insufficient to permit conclusions regarding the influence of hereditary factors [books.google.com]

Procedure Overview There are two general treatment categories of meningioma: traditional surgery and stereotactic radiosurgery. Each may be used alone or in combination, depending on your treatment needs. [neurosurgeonsofnewjersey.com]

This can make it hard to predict how you will feel during treatment. As you prepare to start treatment, it is normal to fear treatment-related side effects. [cancer.net]

Treatment is dictated by the tumor's location and patient's symptoms. [aans.org]

Prognosis Most are benign - usu. a good prognosis. Even benign tumors may show extensive local spread - considerable morbidity and mortality. Metastases are rare and then usu. after surgery. May be malignant - bad prognosis. [librepathology.org]

In this section: Definition Symptoms Diagnosis Treatment Prognosis MRI image showing a typical meningioma tumor A meningioma is a tumor that arises from a layer of tissue (the meninges) that covers the brain and spine. [neurosurgery.ucla.edu]

It acts as a tumor suppressor in glioblastoma, and functions as a marker for prognosis in gliomas. In children below three years of age, mutations in this gene are linked to desmoplastic medulloblastoma. [sigmaaldrich.com]

If the meningioma does begin to grow, doctors may intervene with surgery, or radiation if the tumor is in a hard to access area, and the prognosis is ‘excellent’ if the tumor is removed entirely. [foxnews.com]

Heredity, environment, the role of infectious agents, and other influences have been cited within a multiplicity of factors of possible relevance to the problem of neoplasm etiology. [books.google.com]

It is possible that other genic mutations resulting in aberrant activation of the Hh pathway might underlie meningioma predisposition in families with an unknown etiology. Copyright 2012 The American Society of Human Genetics. [ncbi.nlm.nih.gov]

It is possible that other genic mutations resulting in aberrant activation of the Hh pathway might underlie meningioma predisposition in families with an unknown etiology. [escholar.manchester.ac.uk]

Conclusion Genome profiling using array CGH can be a valuable complement to histopathology for routine tumor diagnosis and grading and for implicating etiology of meningiomas. [bmcmedgenomics.biomedcentral.com]

Etiology Multiple meningiomas were initially reported to be related to the NF2 gene mutation with a clonal spread across the meninges 4), but might also correspond to mosaic NF2 cases 5) 6) 7). It can occur as familial multiple meningioma. [operativeneurosurgery.com]

The authors collected clinical, imaging, histological, and treatment data to obtain information on epidemiology, management options, and outcomes of active treatment and surveillance. [thejns.org]

Radiation can shrink the tumor or help prevent it from growing any larger. Radiation can also be used to kill cancer cells if the tumor is malignant. It may also be used on the parts of a tumor the surgeon was unable to remove. [webmd.com]
