Well-defined, sellar and suprasellar mass lesion causing expansion of the sella. It has peripheral solid and central cystic components, as well as few calcifications. Solid components show moderate enhancement on the post-contrast study. Superiorly, the lesion is compressing both optic nerves and optic chiasma, and extending into the 3rd ventricle, leading to obstructive hydrocephalus. Internal carotid arteries are seen at its periphery and are not encased.
