Medulloblastoma

Medulloblastoma is a rare, malignant brain tumor. It is most common in children and young adults under age 25. It is a fast-growing tumor and can metastasize (spread) to other parts of the brain and spine.

Symptoms of medulloblastoma

Medulloblastomas cause swelling in the brain, which can lead to the following brain tumor symptoms:

  • Vomiting, especially in the morning
  • Increasing head size
  • Excessive sleepiness
  • Irritability
  • Refusal to eat
  • Eye drooping
  • Eye movement problems and/or double vision
  • Headaches
  • Impaired bowel and bladder function
  • Seizures
  • Weakness in the legs

Having these symptoms does not mean your child has a brain tumor. Many other conditions have similar symptoms. Your doctor at Rush can help you determine the root of your child’s problem.

Medulloblastoma: what you should know

  • Medulloblastoma is a type of primitive neuroectodermal tumor (PNET), a group of rare brain tumors that can occur anywhere in the brain.
  • Medulloblastomas occur in the lower, back part of the brain. They are the most common malignant brain tumors in children.
  • It is rare for medulloblastomas to spread beyond the central nervous system (brain and spine).
  • Brain and spinal cord tumors are the third most common type of childhood cancer, after leukemia and lymphoma.
  • Because their brains and spines are still developing, children with brain tumors require different treatment and care than adults. 
  • There are no known causes or risk factors for medulloblastoma.
