There is a 12x15x19 mm well-defined extra-axial solid mass lesion along the tuberculum sellae and sellae turcica which shows homogenous enhancement and a broad dural attachment to the planum sphenoidale.
On plain scans, the mass is seen separate from the pituitary gland and the diaphragm sellae is depressed, indicating this mass is of suprasellar origin.
Adhesion of the mass to the ICA clinoid segments bilaterally and right optic nerve also is seen.
Case Discussion
The important signs of how to distinguish a suprasellar mass from one arising from the pituitary are: a dural tail, depression of the diaphragm sella and separation of the pituitary the mass.
