Overview

Oligodendroglioma is a tumor that can occur in the brain or spinal cord. Oligodendroglioma forms from oligodendrocytes — cells in the brain and spinal cord that produce a substance that protects nerve cells.

Oligodendroglioma can occur at any age, but most often affects adults. Signs and symptoms can include seizures and headaches. Weakness or disability can occur in the part of the body that's controlled by the nerve cells affected by the tumor.

Oligodendroglioma treatment usually involves surgery to remove the tumor. Additional treatments may be necessary if the tumor is aggressive or is more likely to recur.
