Post-operative MRI of the head with and withoutcontrast. Midsagittal (A), axial (B) and coronal (B) imaging suggests an overall interval reduction of the size of the mass within the sella turcica. There is persistent tumor present within the right cavernous sinus. This has maximal measurements of 2.0 cm × 1.3 cm × 0.9 cm. The residual tumor partially encircles the right cavernous internal carotid artery in the same region. There is extension along the posterior cavernous sinus into Meckel's cave and along the dorsal superior clivus adjacent to the basilar artery. Additional extension is seen ventrally along the cranial nerves to abut the posterior optic canal.
