Core Tip

Core Tip: Primary sellar atypical teratoid/rhabdoid tumor (AT/RT) is the most aggressive sellar malignancy and poses grave clinical consequences. Preoperative diagnosis of sellar AT/RT is important for patients and their families and physicians to understand the unfavorable prognosis and to plan management. The imaging features of sellar AT/RT and pituitary macroadenoma largely overlap so that imaging diagnosis of sellar AT/RT is very challenging. Extensive cavernous sinus invasion disproportionate to tumor size may suggest sellar AT/RT. It remains to be explored whether the absence of imaging evidence of remodeling of perisellar structures such as the optic chiasm and cavernous sinus will lead to the diagnosis of sellar AT/RT.
