Patient 2. MR images of the brain on admission. Serial consecutive fat-suppressed fluid-attenuated inversion recovery (a) and gadolinium-enhanced T1-weighted (b) axial images showed an inhomogeneous, irregularly contrast-enhancing mass lesion (arrows) in the right paratrigonal region associated with a marked vasogenic edema, resulting in a mass effect. Also note the sellar and suprasellar macroadenoma (white arrowheads), which is shown better on the gadolinium-enhanced T1-weighted sagittal image (c), and a left frontal meningioma (black arrowhead).
