Oligodendroglioma arise mainly in the frontal lobe and in 50–80% of cases, the first symptom is the onset of seizure activity, without having any symptoms beforehand. [2] Headaches combined with increased intracranial pressure are also a common symptom of oligodendroglioma.
OLIG2 is well recognized for its importance in cancer research, particularly in brain tumors and leukemia.OLIG2 is universally expressed in glioblastoma and other diffuse gliomas (astrocytomas, oligodendrogliomas and oligoastrocytomas), and is a useful positive diagnostic marker of these brain tumors. [13]
Oligoastrocytomas are a subset of brain tumors that present with an appearance of mixed glial cell origin, astrocytoma and oligodendroglioma. [1] However, the term "Oligoastrocytoma" is now considered obsolete by the National Comprehensive Cancer Network [2] stating "the term should no longer be used as such morphologically ambiguous tumors can be reliably resolved into astrocytomas and ...
Anaplastic oligodendroglioma is a neuroepithelial tumor which is believed to originate from oligodendrocytes, a cell type of the glia. In the World Health Organization (WHO) classification of brain tumors, anaplastic oligodendrogliomas are classified as grade III. [ 2 ]

A glioma is a type of primary tumor that starts in the glial cells of the brain or spinal cord.They are cancerous but some are extremely slow to develop. [2] [3] Gliomas comprise about 30 percent of all brain tumors and central nervous system tumours, and 80 percent of all malignant brain tumours.
Classification of brainstem gliomas by MRI appearance. Histopathology of a brainstem glioma. A brainstem glioma is a cancerous glioma tumor in the brainstem.Around 75% are diagnosed in children and young adults under the age of twenty, but have been known to affect older adults as well. [1]
