Figure 2: In T1 coronal image (a), the mass is homogeneously (arrow) T1 iso-intense. In postcontrast T1 coronal (b), axial (c), and sagittal (d) images, the entire lesion shows homogenous contrast enhancement, with involvement [arrows in (b)] of the hypothalamus and extension across the foramen rotundum. There is infiltration of left Meckel's cave and cisternal segment of the left trigeminal nerve [arrow in (c)]. The enhancing lesion extends to the sphenoid sinus, clivus, prepontine cistern, and over the planum sphenoidale (d)
