Giant lumbar paraspinal atypical teratoid/rhabdoid tumor in a child

Atypical teratoid/rhabdoid tumor (AT/RT) is a highly aggressive and uncommon tumor of the central nervous system, primarily affecting young children. AT/RT of the paraspinal region with involvement of the spine and spinal cord is extremely rare, with only few case reports in the literature. We report an unusual case of giant lumbar paraspinal AT/RT with intraspinal extension in a previously healthy 18-month-old female child. To the best of our knowledge, this kind of presentation has not been reported previously in the English literature.
