According to the American Cancer Society, about 30% of brain tumors are gliomas, a fast-growing, treatment-resistant type of tumor that includes glioblastomas, astrocytomas, oligodendrogliomas
, and ependymomas.
Based on CT appearance alone, calcified gangliogliomas may be indistinguishable from oligodendrogliomas
About High-Grade Gliomas High-grade gliomas, including anaplastic astrocytomas, anaplastic oligodendrogliomas
, and glioblastomas, are the most common and most aggressive primary brain tumors.
granular cell tumors or malignant reticuloses, oligodendrogliomas
Other tumours were the final diagnosis in 7 patients (3 oligodendrogliomas
, 2 meningiomas, 1 dysembryoplastic neuroepithelial tumour (DNET) and 1 ganglioglioma) while 'tumour-like lesions' was the final diagnosis in 3 lesions initially believed to be brain tumours on conventional MRI (infarction secondary to vasculitis, radiation injury and brain abscess).
are part of the infiltrating glial neoplasms and, as such, are characterized by secondary structures of Scherer, which are perineuronal satellitosis, perivascular satellitosis, subpial aggregation, and infiltration of white matter tracts.
are unusual among brain tumors because they often respond to chemotherapy drugs.
2003) contains expression levels of 12625 genes of 50 gliomas samples: 28 glioblastomas and 22 anaplastic oligodendrogliomas
divided into two subsets of classic and non-classic gliomas.

are primary malignant brain tumors originating in the central nervous system (CNS).
The gold surface enabled differentiation of healthy brain from glial tumor formations including glioblastomas and oligodendrogliomas
The first step is extraction of DNA from blood and tumor tissue of patients with one of five types of brain tumors: glioblastomas, anaplastic astrocytomas, mixed gliomas, low grade oligodendrogliomas
, and anaplastic oligodendrogliomas
