MRI
Right parasellar mass centred on the cavernous sinus encasing completely the internal carotid artery. It displays an isosignal to the cortical grey matter on T1, T2 and FLAIR with a vivid homogeneous enhancement on postcontrast sequences. No calcification or haemorrhagic component is seen on the GE sequence.
There is a medial extension to the sellar region compressing the pituitary gland as well as to the sphenoid sinus and suprasellar cistern compressing the optic chiasma.
Posteriorly, there is extension to the retroclival prepontine space compressing the right aspect of the pons with dural thickening and enhancement.
Anteriorly, there is an extension to the inferior orbital fissure and intraconal space.
Complete obliteration of the ipsilateral internal carotid artery on the MRA.
Another small enhancing extra-axial lesion is noted in the right frontal region (small meningioma).
