Medulloblastoma Diagnosis

Medulloblastoma is initially diagnosed after an MRI or CT scan of the brain finds a tumor in the cerebellum (the lower, back part of the brain). Tumors in this region can be of several types, so the final diagnosis cannot be made until the tumor has been removed and the tissue reviewed by a neuropathologist.

Medulloblastoma Staging

(source: National Cancer Institute)

Staging is the process used to find out how much cancer there is and if cancer has spread. It is important to know the stage in order to plan treatment. There is no standard staging system for childhood medulloblastoma and other central nervous system embryonal tumors. Instead, treatment depends on the child’s risk group.

Average Risk

Medulloblastoma is called average risk when all of the following are true:

  • The child is older than 3 years of age
  • All of the tumor was removed by surgery or there was only a very small amount remaining
  • The cancer has not spread to other parts of the body

High Risk

Medulloblastoma is called high risk if any of the following are true:

  • The child is 3 years of age or younger
  • Some of the tumor was not removed by surgery
  • The cancer has spread to other parts of the body

In general, cancer is more likely to recur (come back) in patients in the high-risk group.

A recurrent medulloblastoma is a tumor that recurs (comes back) after being treated. Medulloblastoma most often recurs within 18 months after treatment but may come back many years later. Recurrent tumors may come back in the same place as the original tumor, or in a different place in the brain or spinal cord.
