[Abstract] Objective To investigate the imaging findings of central nervous system (CNS) atypical teratoid / rhabdoid tumor (AT/RT) in children and to improve the diagnostic level of AT/RT. Materials andMethods The clinical and image data of 9 children with AT/RT were analyzed retrospectively.Results The median age of patients was 19 months, 5 cases were infratentorial, 1 case was supratentorial, 3 cases involved both supratentorial and infratentorial. The maximum diameter of the tumor was 49.9±18.3 mm, 7 cases with peripheral tumor cysts and 6 cases with intratumoral hemorrhage,3 cases with brain metastasis,1 with both brain and spinal cord metastasis. The solid components of the tumor were mainly iso-or high-density on CT, MRI showed mixed intensity on T2WI and high intensity on DWI with low ADC value, the tumor showed various enhancement modes.Conclusion CNS AT/RT of children have some relatively specific imaging findings, which is helpful for diagnosis.
