There is a suprasellar mass with peripheral calcification. The central component of the mass is of low density (HU 15). The pituitary is of normal size and seen separate to the mass.
No erosion or remodelling of the bone adjacent to the mass and no extension into the sphenoid sinus. Mass abuts the basilar artery and distorts the optic chiasm.
No hydrocephalus. The remainder of the brain is unremarkable. Mucosal polyp within the left maxillary sinus. Nasal meati are patent with no significant septal deviation. Sphenoid sinus is well aerated. Anterior clinoid processes are non-aerated.
Conclusion: Suprasellar mass most likely represents a craniopharyngioma although correlation with MRI images is recommended.
