Astrocytoma (Brain Tumors)
Oligodendroglioma tumors originate in the glial tissue that supports the brain. They are distinguised from astrocytoma tumors by their shape. Whereas astrocytoma tumors have "long arms," oligodendroglioma tumors are compact. They resemble fried eggs when viewed in a microscope.
Oligodendroglioma tumors can be grade 2 or grade 3. They occur most frequently in young and middle-aged adults but are seen in children, as well.
Seizures are the most common initial symptom for oligodendroglioma tumors.
Oligodendroglioma tumors usually are found in the cerebral hemisphere, and often in the brain's frontal lobe. Surgery to completely remove the tumor is the optimal treatment but tumor location sometimes makes full tumor removal difficult.
Radiation therapy is an option if surgery does not remove the entire tumor.

Following initial treatment physicians will use follow-up magnetic resonance imaging (MRI) screens staggered at consistent intervals to watch for recurrence.
