Heterogeneous mass in sellar and suprasellar region, predominantly cystic with solid component that shows enhancement. There is no restriction to diffusion. At the suprasellar level it displaces the optic chiasm and recesses of the third ventricle without hydrocephalus. The mass extends towards the prepontine cistern, displacing the brainstem and enveloping the basilar artery. There are areas with susceptibility artifacts corresponding to calcifications seen at CT. Note the misplaced probe.
