Living with Gangliocytoma

A rare, usually slow-growing tumor of the brain or spinal cord made of mature nerve cells, often linked to seizures.

Understanding Gangliocytoma

Gangliocytoma is a rare tumor of the central nervous system (CNS) made up of mature nerve cells (neurons).

The most common site is the temporal lobe of the brain, but it can arise anywhere in the CNS, including the cerebellum, brainstem, and spinal cord. It is among the tumors most often tied to epilepsy. These tumors are generally slow-growing and usually do not become malignant. It can occur at a variety of ages.

Signs & symptoms

Symptoms depend on where the tumor is. GARD lists these among the most common:

  • Seizures (most common)
  • Headache
  • Loss of half of the field of vision (hemianopia)
  • Increased pressure in the brain
  • Hormone (endocrine) problems

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
