Summary of


Oligodendroglioma is a primary central nervous system (CNS) tumor. This means it begins in the brain or spinal cord.

Oligodendrogliomas are grouped in two grades based on their characteristics.

  1. Grade II oligodendrogliomas are low grade tumors. This means the tumor cells grow slowly and invade nearby normal tissue. In many cases, they form years before being diagnosed as no symptoms appear.
  2. Grade III oligodendrogliomas are malignant (cancerous). This means they are fast-growing tumors. They are called anaplastic oligodendriogliomas

Oligodendrogliomas occur most often in people between the ages of 35 and 44, but can occur at any age. Oligodendrogliomas occur more often in males and are rare in children. They are most common in white and non-hispanic people.
