Importance of symptoms acuity for clinical diagnosis of primary sellar atypical teratoid/rhabdoid tumor

Table 2 Sellar compression symptoms, pituitary hormone status, and pituitary magnetic resonance imaging findings of major sellar lesions

	Acuity of sellar compression symptoms	Pituitary hormone status	Pituitary MRI	Other clinical clues
Apoplexy	Hyperacute (hours)	Hypopituitarism	With hemorrhage	Known history of pituitary adenoma
Sellar AT/RT	Acute (days to weeks)	Hypopituitarism	Invasive mass	Predominantly in females
Pituitary adenoma	Chronic (months)	Pituitary hormone excess or deficiency	Noninvasive or invasive	History of genetic syndromes
Sellar lymphoma	Chronic (months)	Hypopituitarism	Invasive mass	Unclear
Sellar metastasis	Chronic (months)	Hypopituitarism	Invasive mass	Known malignancies
Hypophysitis	Chronic (months)	Hypopituitarism	Thickened stalk	Postpartum females

MRI: Magnetic resonance imaging; AT/RT: Atypical teratoid/rhabdoid tumor.
