There is a suprasellar solid tumour measuring about 2 cm with an attenuation similar to brain (30-40 HU).
Pituitary macroadenomas are the most common suprasellar mass in adults, and responsible for the majority of transsphenoidal hypophysectomys. They are defined a as pituitary adenomas greater than 10 mm in size and are approximately twice as common as pituitary microadenomas.
This patient underwent surgical removal of the mass and pathology confirmed the diagnosis.
