About Ganglioglioma Brain Tumor

A Ganglioglioma is rare brain tumor that commonly causes seizures.


  • Seizures can be present for months or years before the diagnosis is made.


  • The diagnosis is usually suspected on a magnetic resonance imaging (MRI) scan.
  • Confirmation requires biopsy and resection


MRI showing Ganglioglioma
The MRI image shows a ganglioglioma in the right temporal lobe (arrow). Using precise microsurgical techniques and aided by intra-operative MRI, an image-complete resection was successfully accomplished and the patient had fewer seizures.
  • Seizure management
    • Management may be complex due to difficult-to-control seizures.
    • May require a neurologist specializing in epilepsy.
    • Surgical removal of the tumor is often the best way to control seizures


  • More than 95 percent of gangliogliomas are low grade and usually do not recur after removal.
