Oligodendroglioma is a rare type of glioma brain tumor that develops from cells called oligodendrocytes, which produce the fatty covering that insulates the electrical transmission carried by nerve cells.
Often formed in the frontal or temporal lobes, an oligodendroglioma tumor may originate as a benign growth, but over time it can develop into a malignant lesion.
The location of the tumor produces different symptoms. In the frontal lobe, a tumor may affect mood and personality and possibly cause paralysis on one side of the body. In the temporal lobe, a tumor may affect coordination, speech, and memory.
