Evidence of sellar and suprasellar mass lesion, measuring 2.4 x 2.8 x 3.6 cm in AP, SS and CC dimensions. It is iso to hypointense on T1WI and hyperintense on T2WI and FLAIR. It shows restricted diffusion on DWI reflecting its high cellularity. It shows thin enhancing upper margin representing compressed pituitary gland parenchyma.
Extensions and mass effect:
- laterally, it is partially encasing both internal carotid arteries at the cavernous sinus bilaterally
- inferiorly, expanding the sellar cavity and its floor compressing both sphenoid sinuses with no intrasinus extensions
- superiorly, it is markedly compressing the optic chiasm and both optic tracts, more on the left
