Pituitary mass, which is centrally non-enhancing, with intrinsic regions of high T1 signal suggestive of blood product is again demonstrated, with associated remodelling enlargement the pituitary fossa and extension superiorly into the suprasellar cistern abutting and compressing the chiasm.

Normal flow voids are noted within the internal carotid arteries.
