What is Atypical Teratoid Rhabdoid Tumor (ATRT)?

  • Atypical teratoid rhabdoid tumors (ATRT) are very rare, aggressive tumors of the central nervous system, occurring mostly in the cerebellum (the part of the brain that controls movement and balance) or the brain stem (the part of the brain that controls basic body functions).

    • ATRTs usually occur by age 3, but sometimes are found in older children. ATRTs represent only 1 to 2 percent of childhood brain tumors.
    • These tumors are part of a larger group of malignant tumors called rhabdoid tumors, which also can occur outside the brain.
    • ATRTs may be localized to one part of the brain, or they can spread to other locations in the brain, spine or body.
