Pediatric Atypical Teratoid Rhabdoid Tumor (ATRT)
An atypical teratoid rhabdoid tumor (ATRT) is a rare, fast-growing tumor of the brain and spinal cord.
An atypical teratoid rhabdoid tumor (ATRT) is a rare, fast-growing tumor that is malignant (cancerous) and develops in the brain and spinal cord. This condition is usually seen in children under age 3, but it can also occur in older children and into adulthood.
Experts believe that ATRT results from a gene mutation that causes proteins that stop tumor growth to not develop.
The signs and symptoms of ATRT include:
- Headaches in the morning
- Headaches that are less painful after the child vomits
- Increase in head size (in infants birth to 1 year*)
- Lethargy (lack of energy)
- Nausea and vomiting
- Problems with balance
- Problems with coordination and walking
*Age of infants as defined by the World Health Organization (WHO).
