Atypical Teratoid Rhaboid Tumor (ATRT)

Printer Friendly

ATRTs are rare, high-grade tumors that occur most often in children age 3 and younger. They tend to be fast-growing and frequently spread through the central nervous system.



About half of ATRTs are found in the cerebellum or brain stem. However, they may appear anywhere in the brain or spinal cord.



An ATRT can appear as a large, bulky mass.



Symptoms depend on the age of the patient, as well as the size and location of the tumor. They may include: morning headache or headache that goes away after vomiting, nausea and vomiting, unusual sleepiness or change in activity level, loss of balance, lack of coordination, or trouble walking, and increased head size (in infants).1



ATRTs are rare. They typically occur in children age 3 and younger.



Like many tumor types, the exact cause of ATRT is not known.



Treatment generally involves surgery to remove the tumor followed by chemotherapy. Radiation may be considered depending on the age of the patient and whether the tumor has recurred.
