What are the symptoms and signs of medulloblastoma?

Children with medulloblastoma may experience one or more of the following symptoms or signs. Symptoms are changes that you can feel in your body. Signs are changes in something measured, like taking your blood pressure or doing a lab test. Together, symptoms and signs can help describe a medical problem. Sometimes, children with medulloblastoma do not have any of the symptoms and signs described below. Or, the cause of a symptom or sign may be a medical condition that is not a brain tumor.

  • Headaches

  • Morning vomiting that worsens over time

  • Clumsiness

  • Problems with handwriting and other motor skills that worsen over time

  • Problems with vision or an eye turning inwards

If medulloblastoma spreads to the spinal cord, it may cause the following symptoms:

  • Back pain

  • Inability to control the bowels and bladder

  • Difficulty walking

If you are concerned about any changes your child experiences, please talk with your child’s doctor. The doctor will try to understand what is causing your child’s symptom(s). They may do an exam and order tests to understand the cause of the problem, which is called a diagnosis.

If a brain tumor is diagnosed, relieving symptoms remains an important part of your child’s care and treatment. Managing symptoms may also be called "palliative and supportive care," which is not the same as hospice care given at the end of life. This type of care focuses on managing symptoms and supporting people who face serious illnesses, such as cancer. You can receive palliative and supportive care at any time during cancer treatment. Learn more in this guide’s section on Coping with Treatment.

Be sure to talk with your child’s health care team about the symptoms your child experiences, including any new symptoms or a change in symptoms.
