CT
A large soft tissue mass expands the clivus and sella turcica, causing bony destruction and obliteration of the sphenoid sinuses, with extension into the suprasellar cistern. The clivus is eroded and not well maintained. The mass extends into the pontine cistern.
It is slightly hyperdense on the non-enhanced CT and there are foci of calcifications. Post-contrast images show diffuse enhancement.
