Under the microscope, these tumor cells appear to have “shortarms,” or a fried-egg shape. The exact cause of oligodendroglioma brain tumors is unknown.[disabilityspecialists.net]
Under the microscope, these tumor cells appear to have “shortarms,” or a fried-egg shape. Sometimes oligodendrogliomas are mixed with other cell types.[abta.org]

What is the prognosis of an oligodendroglioma? Prognosis in relation to brain tumours is an average number, given in months or years that a patient is likely to survive for, following diagnosis.[thebraintumourcharity.org]
Prognosis A prognosis is an estimate of the likely progress of a disease after a diagnosis, based on an average patient group.[braintumour.ca]
Currently, the factors listed above are the best indicators of a patient’s prognosis.[cancer.net]
