An introduction to the issue of a brain tumor

Thus the disruption of the BBB, which can be detected by MRI and CT, is regarded as the main diagnostic indicator for malignant gliomas, meningiomas, and brain metastases.

Interdisciplinary management of central nervous system metastasis and neoplastic meningitis: This issue contains a mixture of clinical and preclinical scholarly articles that have been written by scientists from America, Europe, and the Middle East.

Brain tumor cell invasion and metastasis: Brain tumors have similar characteristics and obstacles when it comes to diagnosis and therapy with tumors located elsewhere in the body. Pressure areas where the brain tissue has been compressed by a tumor also appear hyperintense on T2-weighted scans and might indicate the presence a diffuse neoplasm due to an unclear outline.

Increased intracranial pressure ICP may be attributable to the direct mass effect of the tumor, increased blood volume, or increased cerebrospinal fluid CSF volume, which may, in turn, have secondary symptoms. Anaplastic cells have lost total control of their normal functions and many have deteriorated cell structures.

Characteristics of malignant tumors include: However, for clarity, the articles that follow adhere to a convention that they mean slightly different things; this convention is not followed outside these articles: Clinical and laboratory investigations will serve to exclude infections as the cause of the symptoms.

This means that a cancerous neoplasm has developed in another organ elsewhere in the body and that cancer cells have leaked from that primary tumor and then entered the lymphatic system and blood vessels. More generally a neoplasm may cause release of metabolic end products e. Such mental and cognitive difficulties might be caused by before, after, or during the surgery problems.

The patients have glioma brain tumor, between the age ranges, diagnosed by WHO criteria, none had the history of prior psychological and neurological illness or surgery, not being or were treated with chemotherapy or radiotherapy before the surgery.

The use of electroencephalography EEG often plays a role in the diagnosis of brain tumors. The maximum score in this test is 30 that a score lower than 23 are indicating a cognitive disorder [ 20 ]. These two types are equally numerous in the brain as a whole, although glial cells outnumber neurons roughly 4 to 1 in the cerebral cortex.

The excluding from the study criteria were: Significance of the abnormality is highly dependent on context.

Switzerland This article reviews the in vitro and ex vivo techniques used to study growth and dissemination of brain cancer cells including organotypic slice culture methods.

Cells can become anaplastic in two ways:Brain Tumors: an Introduction. Figure 1. Brain tumors compress and displace normal brain tissue.

A brain tumor is a growth of abnormal cells inside the brain. Most brain tumors that children get are called primary brain tumors, meaning that they originated in the brain and did not spread from somewhere else.

Medical Illustrations. Statistics. Risk Factors. Symptoms and Signs. Diagnosis. Grades and Prognostic Factors. A secondary brain tumor is a cancerous tumor that started in another part of the body, such as the breast, lung, or colon, and then spread to the brain.

If cancer spreads to the meninges and the cerebrospinal fluid (CSF), it is called leptomeningeal metastases or neoplastic meningitis.
