Note is made of bone expansion, with ground-glass opacity in the sphenoid sinus region with sclerotic rim, involving the base of the skull, causing regional mass effect, obliterating both sphenoid sinuses, indenting the left optic canal, subsequently compressing intracanalicular part of the optic nerve.

Ground-glass attenuation of sphenoid bone likely sphenoid bone fibrous dysplasia.
