Types & Subtypes
Ganglioglioma
Ganglioglioma is a usually low-grade glioneuronal tumor that commonly causes seizures and is often cured by surgery.
In short: Ganglioglioma
- It is a usually low-grade glioneuronal tumor.
- It contains both abnormal neurons and glial cells.
- It commonly causes seizures, often in the temporal lobe.
- It is often cured by surgical removal.
What it is
Ganglioglioma is a usually low-grade (WHO grade 1) tumor that contains both abnormal neurons (ganglion cells) and glial cells — making it a glioneuronal tumor. It commonly causes seizures, often arising in the temporal lobe, and is frequently cured by surgical removal.
Understanding Ganglioglioma
Ganglioglioma is one of the most common tumors associated with chronic epilepsy, frequently found during the evaluation of seizures that are difficult to control. It contains a mix of neuronal and glial elements and usually behaves in a benign, slow-growing manner. Because it is typically low-grade and relatively localized, surgery to remove it is the main treatment and is often curative — and removing the tumor frequently improves or resolves the seizures. Some gangliogliomas carry a BRAF V600E mutation, which can be relevant in uncommon cases that recur or behave more aggressively. The outlook is generally favorable. Understanding ganglioglioma clarifies a common, favorable, seizure-associated glioneuronal tumor usually cured by surgery.
Why it matters
Understanding ganglioglioma helps patients and families see a favorable glioneuronal tumor — a common cause of epilepsy that is often cured by surgery, which can also improve the seizures.
Common questions
What is a ganglioglioma?

Often — by surgical removal.
Bottom line
Ganglioglioma is a usually low-grade glioneuronal tumor that commonly causes seizures and is often cured by surgery, which can also improve the seizures.
