What is Oligodendroglioma Of The Brain?Oligodendroglioma is a rare tumor (abnormal cell proliferation) that arises from the brain and spinal cord. Oligodendroglioma develops from oligodendrocytes. Oligodendrocytes are cells in the brain and spinal cord that form a protective sheath around the nerves.
Disease EtiologyThere is no exact well-known cause; however certain genetic mutations (alteration in genes) and exposure to certain radiations or radiation therapy are the risk factors for the development of oligodendroglioma brain.
Disease EpidemiologyThese are rare tumors, accounting for about 4% of all primary brain tumors. It usually develops in people between the ages of 35 and 40, but it can affect people of any age. Oligodendrogliomas slightly predominate in men and rarely develop in children. People of white ethnicity are more likely to develop oligodendrogliomas than people of black ethnicity.
Signs and SymptomsThe symptom of oligodendroglioma depends on the site of origin and size of the tumor. The patient may suffer from the following signs and symptoms. These are
- Seizures (Fits)
- Body weakness
- Numbness of the body
- Problems with balance and movement
- Behavior changes
- Changes in personality
DiagnosisThe following diagnostic tests and procedures can be used to make a diagnosis. These are
- Imaging tests such as X-Ray, CT-scan (computerized tomography), PET-scan (Positron emission tomography) help detect the site, size, and location of the tumor.
- Tumor biopsy and histopathological examination
