Brain tumors and intracranial. Medical search. Frequent questions

Slightly more common in men than in women, malignant brain tumors (gliomas, meningiomas, and schwannomas) have an overall incidence of 4.5 per 100,000. (online-family-doctor.com)
In adults, incidence is highest between ages 40 and 60, and the most common tumor types are gliomas and meningiomas. (online-family-doctor.com)
Gliomas, the most common primary brain neoplasms in adults, are very heterogeneous tumors. (ajnr.org)
High-grade gliomas can be highly invasive and extremely vascular tumors. (ajnr.org)
Two of the most important factors in determining the malignancy of gliomas are their ability to infiltrate the brain parenchyma and to recruit or synthesize vascular networks for further growth (ie, neoangiogenesis). (ajnr.org)
3 Most gliomas, especially high-grade ones, show a high degree of regional heterogeneity within the tumor based on tumor cellularity, edema, and necrosis. (ajnr.org)

Meningiomas (arising from the meninges, a neural crest-derived cell) are the most common brain tumor of dogs, accounting for 40% of all primary brain tumors. (wikipedia.org)
In meningiomas, one feature may be dominant over the other, and this phenomenon partly contributes to the rich diversification of histologic patterns in these tumors. (medscape.com)
Similar to other tumors, the risk factors for the development of meningiomas can be divided into those with clearly defined genetic etiology and those that are attributed to environmental and other nongenetic factors. (medscape.com)
Glial cell tumors and pituitary tumors occur commonly in brachycephalic breeds, whereas meningiomas occur most frequently in dolichocephalic breeds. (vin.com)
Primary tumors other than meningiomas appear to be less common in cats than in dogs. (vin.com)
Meningiomas are tumors of the meninges that can compress adjacent brain tissue. (msdmanuals.com)
Meningiomas are the only brain tumor more common among women. (msdmanuals.com)

Affected individuals also have an increased risk of developing a type of brain cancer called a glioma. (medlineplus.gov)
In vivo perfusion imaging techniques provide additional information regarding tumor physiology and hemodynamics, which may help in better characterizing glioma malignancy and may also overcome some of the limitations of histologic grading and conventional morphologic imaging. (ajnr.org)
3 - 5 However, PCT, which has also been used recently for glioma grading, 6 , 7 provides a linear relationship between tissue attenuation and tissue concentration of a contrast agent, unlike perfusion MR imaging, and, hence, probably provides a more robust and less biased estimation of hemodynamic (tumor blood volume) and physiologic (tumor vascular leakiness) parameters.

Resection and whole brain radiotherapy (WBRT) are the standards of care for the treatment of patients with brain metastases (BM) but are often associated with cognitive side effects. (researchgate.net)
For schwannomas, microsurgical technique allows complete resection of the tumor and preservation of the facial nerve. (online-family-doctor.com)
Within this range, there is complex decision making to maximize safe resection whilst minimizing morbidity which depends on two main factors: tumor type (influencing propensity for recurrence, metastasis, overall survival and the need for adjuvant therapies), and tumor location (proximity to eloquent areas of brain and vital neurovascular, or neuroendocrine structures). (frontiersin.org)
Software can be used to mark out the tumor extent and a resection plan which can be used intraoperatively to navigate to the tumor. (frontiersin.org)
Tracts may be for example within tumor, abutting the tumor, or split by the tumor, which may impact the decision of both resection extent and direction of approach (Figure 1 ). (frontiersin.org)
The inability to perform complete surgical tumor resection and poor drug delivery to the brain contribute notably to the limited treatment options. (hindawi.com)

This is called raised intracranial pressure. (macmillan.org.uk)

The respiratory depression involves a reduction in the responsiveness of the brain stem respiratory centers to both increases in carbon dioxide tension and electrical stimulation. (nih.gov)
Craniocervical junction abnormalities are congenital or acquired abnormalities of the occipital bone, foramen magnum, or first two cervical vertebrae that decrease the space for the lower brain stem and cervical cord. (merckmanuals.com)
Hearing loss involves the cerebellomedullary region, the brain stem, or temporal lobes of the cerebrum. (vin.com)
They are close to critical brain areas (eg, brain stem). (msdmanuals.com)

Studies are underway to use and develop the dog as a model of this devastating disease of humans in the hope that characterizing and successfully treating these tumors in dogs may lead to improved therapies for humans afflicted with this disease. (wikipedia.org)

Most ovarian germ cell tumors are benign mature teratomas (dermoid cysts). (cigna.com)
Most of these tumors are benign teratomas in the sacrum or coccyx. (cigna.com)

International experts show how to generate state-of-the-art images and define diagnoses from crucial clinical/pathologic MR imaging correlations for neurologic, neurosurgical, and psychiatric diseases spanning fetal CNS anomalies to disorders of the aging brain. (chipsbooks.com)
Hence, there is a need for noninvasive in vivo clinical imaging tools that can study perfusion in the entire tumor, can be used to assess much larger volumes than small biopsy samples, and can probably guide biopsy and excision sites for better results. (ajnr.org)
Even with a slowly progressive tumor, clinical signs may progress rapidly when compensatory mechanisms have been exhausted. (vin.com)

Astrocytomas are the most common neuroectodermal tumor of dogs. (wikipedia.org)
Pituitary gland tumors are very common in the canine. (wikipedia.org)
Ovarian germ cell tumors are more common in adolescent girls and young women. (cigna.com)
2 cm in diameter, are among the most common intracranial tumors. (msdmanuals.com)
[ 4 ] These tumors are twice as common in women, and there is a regional variation. (medscape.com)

Another hypothesis involves the release of natriuretic factors, possibly including brain natriuretic peptide (C-type natriuretic peptide) or urodilatin by the injured brain. (medscape.com)

The brain and spinal cord abnormalities associated with ECCL can cause seizures, abnormal tensing of the muscles, and intellectual disability ranging from mild to profound. (medlineplus.gov)
However, seizures can also be caused by problems other than brain abnormalities. (purina.com)
Idiopathic epilepsy in cats also manifests through seizures, but in this case, no abnormalities can be detected in the brain or anywhere else in the body. (purina.com)
Bone abnormalities (eg, brain atrophy, hyperostosis around the cerebral convexities, changes in the tuberculum sellae) may be seen incidentally on CT or plain x-rays. (msdmanuals.com)

use stereotactic radiosurgery if tumor remains after excision or cannot be excised completely. (msdmanuals.com)

Neuro-navigation is used to plan biopsy entry sites, trajectory and the intracranial target. (frontiersin.org)

Method: A retrospective crossectional review of patients with brain tumors in the Neurosurgical Unit of Obafemi Awolowo University Teaching Hospitals Complex, Ile-Ife from January 2003 to December 2007 was conducted. (bvsalud.org)

[ 4 ] Tumors arising in the spinal cord have a distinctly high incidence in women. (medscape.com)
