Having a tumor in the brain or spinal cord is always a very serious matter. An atypical teratoid rhabdoid tumor is an aggressive tumor of the central nervous system. If your child has been diagnosed with AT/RT, there are a number of things that you should know:

  • AT/RT can occur anywhere in the brain but are most commonly found in cerebellum (base of the brain) and brain stem (the part of the brain that controls basic body functions).
  • This type of tumor usually occurs in children under 3 but it can sometimes occur in older children and adults.
  • AT/RT was previous thought to be a type of medulloblastoma. However, it is now known to be a separate type of tumor and is treated differently.
  • AT/RT represents only 1 to 2 percent of childhood brain tumors.
