Enlarged sella with a pituitary adenoma with a suprasellar extension due to a haemorrhagic component. The tumour indents the cavernous sinus on the right without further invasion. The suprasellar component has an intrinsic T1 signal and susceptibility artefact consistent with haemorrhage, also with a hematocrit level within. This pushes the optic chiasm superiorly. Flow void of the ICA is preserved bilaterally. Brain is otherwise normal. Mucosal thickening of the left maxillary and right frontal paranasal sinuses.
