Lobulated cystic mass is centred in the posterior suprasellar region with marginal T1 hyperintensity correlating with calcification seen on CT.
There is irregular enhancement of the periphery of the cysts.
The lesion is separate from the normal-appearing pituitary tissue but is inseparable from the infundibulum which seems to pass from anterior toward the right side of the mass.
The mass abuts the posterior margin of the optic chiasm, splaying and laterally displacing the optic tracts.
It indents the floor of the third ventricle and contacts without compressing or encasing supraclinoid ICAs, ACAs and basilar artery. No pulsation artefact seen in relation to this mass. The remainder of the imaged brain (please note this study has been targeted to the pituitary, and as such the whole brain has not been imaged) appears unremarkable.
Conclusion: Findings are most consistent with a suprasellar adamantinomatous craniopharyngioma.
