Enlarged sella turcica (differential)

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 tumours (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
