Oligodendroglioma is a growth of cells that starts in the brain. The growth of cells, called a tumor, begins in cells called oligodendrocytes. These cells make a substance that protects nerve cells and helps with the flow of electrical signals in the brain and spinal cord. Oligodendroglioma is most common in adults, but it can happen at any age.

Oligodendrogliomas cannot currently be differentiated from other brain lesions solely by their clinical or radiographic appearance. As such, a brain biopsy is the only method of definitive diagnosis. Oligodendrogliomas recapitulate the appearance of the normal resident oligodendroglia of the brain. (Their name derives from the Greek roots

Oligodendrogliomas are rare brain tumors that cause neurological symptoms. Surgery, chemotherapy, and radiation are typical treatment methods for this condition. The five-year survival rate for oligodendrogliomas is encouraging and new therapies are currently being investigated. Getting an accurate diagnosis and the appropriate treatment

Oligodendroglioma (OG) is a type of diffusely infiltrating glioma and constitutes approximately 5% of primary intracranial tumors.[1] They often involve the cortical gray matter and are most commonly seen in the frontal lobes. Historically OG was diagnosed based on the histological appearance of the tumor. However, in 2016 the WHO changed the criteria for the classification of CNS tumors to

Oligodendroglioma is a brain tumor arising from oligodendrocytes, the name for cells that normally wrap around and provide support to nerve fibers in the brain. These tumors can develop anywhere in the brain, but are more commonly found in the frontal and temporal lobes. Because oligodendrocytes are a type of glial cell, oligodendrogliomas are

Oligodendrogliomas can be identified by deficiencies in certain chromosomes named 1p and 19q. Genetic profiling of oligodendrogliomas provides a more accurate predictor of prognosis and treatment options than does standard pathology. Please speak with your health care provider for more information about your tumor type, biomarkers, and

https://www.abta.org/tumor_types/oligodendroglioma/
Oligodendrogliomas are a type of glioma that have mutations in one of two genes called IDH1 and IDH2 and are missing the two chromosomal arms, 1p and 19q. These tumors are thus named Oligodendroglioma, IDH-mutant, and 1p/19q-codeleted. Oligodendrogliomas are defined as either grade 2 or 3, with grade 3 tumors associated with a more rapid growth

https://neurosurgery.weillcornell.org/condition/oligodendroglioma
An oligodendroglioma is a primary brain tumor, meaning it originates in the brain rather than having spread from another location in the body. Most oligodendrogliomas are found in the frontal lobe of the brain, followed by the temporal lobe. They can spread via the cerebrospinal fluid to anywhere in the brain or spine, but they are rarely found outside the central nervous

https://radiopaedia.org/articles/oligodendroglioma
Terminology. Historically, oligodendrogliomas have been defined on purely histological grounds. As of 2016, however, with the update to the WHO classification of CNS tumors the diagnosis of oligodendroglioma is made by identifying a diffuse infiltrating glioma with IDH mutation and 1p19q codeletion 9.This was a very significant change, as the tumors previously diagnosed as oligodendrogliomas

Oligodendrogliomas are primary brain tumours that are a type of glioma. They're the third most-common glioma, accounting for around 3% of all primary brain tumours and 5-18% of gliomas. The majority of oligodendrogliomas occur in the frontal lobe. The second most common site affected is the temporal lobe, followed by the parietal lobe.

The "diffuse glioneuronal tumor with oligodendroglioma-like features and nuclear clusters" (DGONC) is a new tumor type recently isolated by a distinct DNA-methylation profile and introduced in the latest World Health Organization (WHO) Classification of Brain Tumors [1, 2].These tumors frequently harbor a chromosome 14 monosomy [1, 2].To date, 44 cases have been reported in the literature

https://www.neurosurgery.columbia.edu/patient-care/conditions/oligodendrogliomas
Oligodendrogliomas can also have a mutation in the gene IDH1, in which case they have a more favorable prognosis. In general, oligodendrogliomas have a better prognosis and better response to therapies than other infiltrative gliomas. Oligodendrogliomas can develop at any age. They typically develop in young and middle-aged adults and rarely (6

Also known as low-grade gliomas, oligodendrogliomas typically form in the white matter or the outer layer of the brain (cortex), but they can occur anywhere in the CNS. Though uncommon, the cancer can spread to other areas of the CNS via the cerebrospinal fluid. Oligodendrogliomas rarely spread beyond the CNS to other organs and tissues.

Summary. Oligodendroglioma symptoms include seizures, headaches, memory problems, personality changes, trouble with balance and movement, numbness, weakness, and more. Symptoms may vary depending on the size and location of the tumor. Since symptoms of oligodendroglioma are similar to other types of brain tumors, it's essential to be as

Oligodendrogliomas in children often lack the IDH mutation, TERT promoter mutation, and 1p/19q-codeletion that is observed in their adult counterparts [14, 20]. Instead, they most commonly harbor solitary pathogenic alterations in the FGFR1 oncogene that cause constitutive activation of the kinase domain via gene fusion, tandem duplication, or

Oligodendrogliomas most resemble oligodendrocytes, the cells that encircle and insulate the nerve cells of the brain. Oligodendrogliomas often are more anatomically discrete than astrocytomas, another type of glioma, and they are usually more superficial in the brain. However, oligodendrogliomas are rarely, if ever, cured by surgery alone.

Summary. Oligodendrogliomas are brain tumors arising from oligodendrocytes, a type of cell that makes up the supportive (glial) tissue of the brain. They can be low-grade (grade II) or high-grade (grade III, also called anaplastic). While they can be found anywhere within the cerebral hemisphere, they are most common in the frontal and temporal

Despite recent increase [1-3] the frequency remains only 4 per 100,000 person-years [].Most oligodendrogliomas are diagnosed in the adult population with the peak incidence in the fourth and fifth decades of life [2, 4].Only six percent of oligodendrogliomas are diagnosed in the pediatric or adolescent population [].
