Oligodendrogliomas are uncommon gliomas.

  • They arise from glial cells called oligodendrocytes. These cells are a normal constituent of the brain but much less common than astrocytes.

‘We offer a multidisciplinary management of oligodendroglioma, with experts in neurosurgery, radiation oncology and neuro-oncology working closely together to assure the highest quality of care’.


  • Seizures occur in 50 percent to 80 percent off patients.
  • Other symptoms include headache, nausea and vomiting, ataxia (difficulty with balance), dizziness and altered mental state




  • Magnetic resonance imaging (MRI) is the preferred diagnostic tool, although computed tomography (CT) is important as well to document whether calcifications exist.
  • An actual tissue biopsy is typically required for definitive diagnosis in nearly all cases.


  • Surgery
    • We will determine how much of the tumor can or should be removed. If the tumor is surgically accessible, a “complete” removal is attempted.
    • Sometimes, oligodendroglioma are best removed with the aid of neuronavigation surgery, allowing the most complete, safest surgery possible.
  • Radiation therapy
    • Radiation therapy may be considered after surgical removal.
  • Chemotherapy
    • We offer the latest in promising medical therapies.
    • For anaplastic oligodendroglioma (a more aggressive type of oligodendroglioma), chemotherapy can be very effective if the tumor demonstrates certain chromosomal (gene) defects.
