Enlargement of sella turcica can be seen in situations including the following:
- empty sella syndrome
- slight globular enlargement of the sella with no erosion, destruction or posterior displacement of dorsum sellae
- intracranial hypertension
- enlargement with erosion of anterior cortex of dorsum sellae proceeds to the floor of the sella and may result in complete destruction of the dorsum; erosion of anterior and posterior clinoids can be seen
- pituitary tumors (e.g. macroadenoma)
- ballooned sella with an undercutting anterior clinoid process, unequal downward displacement of the floor (double floor appearance)
- craniopharyngioma
- elongated sella with short curved dorsum is characteristic, but more often indistinguishable from the pituitary lesions
- Rathke's cleft cyst: rarely can cause sellar enlargement if reaches large size
