Symptoms of Medulloblastoma


Medulloblastoma symptoms can vary based on the size of the tumor and where it is located.

Symptoms that may be a sign of pressure within the brain caused by the tumor can include:

  • Headaches that may be occasionally relieved by vomiting, especially early morning vomiting
  • Seizures
  • Vision, hearing, and speech problems
  • Nausea

If the medulloblastoma is in the area of the brain called the cerebellum, symptoms can include:

  • Issues with balance, motor skills, or trouble walking, called ataxia

These symptoms can indicate the medulloblastoma has spread to the spinal cord:

  • Numbness in limbs, called neuropathies — a “pins and needles” feeling
  • Back pain
  • Bowel problems, called incontinence

Other symptoms of medulloblastoma can include:

  • Loss of appetite
  • Changes in personality, mood or behavior
  • Sleepiness
  • Weakness

Symptoms generally get worse over time.

The time from when symptoms first start to diagnosis is usually about two to three months. After diagnosis, surgery options may be recommended to relieve pressure within the brain and alleviate symptoms.
