Oligodendrogliomas account for 2 to 4% of all brain tumors and develop from glial cells called oligodendrocytes, most often in the frontal or temporal lobes of the brain.
While this tumor type usually is incurable, it progresses gradually and allows for prolonged survival. It can occur in children, but is most common in both men and women between 20 and 40 (average age at diagnosis is 35).
CT and/or MRI along with biopsy are used for a definitive diagnosis, and treatment depends on tumor grade. Oligodendroglioma has a high recurrence rate.
