Living with Desmoplastic infantile ganglioglioma

A rare brain tumor in infants, usually in the front or side of the brain, with rapid head growth and a bulging soft spot.

Understanding Desmoplastic infantile ganglioglioma

Desmoplastic infantile ganglioglioma is a rare brain tumor that usually appears in the frontal or parietal lobes of the brain.

It is usually diagnosed before 18 months of age, and most infants have symptoms for only a short time. Seizures are not common. A bulging fontanelle (soft spot), fast head growth, vomiting, and a sunset sign are usually seen.

Signs & symptoms

GARD doesn't list a symptom list. Based on its summary, features include:

  • Bulging soft spot (fontanelle)
  • Rapid head growth
  • Vomiting
  • Eyes that look downward (sunset sign)

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