(a) MRI sagittal T1-weighted, (b) coronal T2-weighted images, (c) coronal T1-weighted images after contrast media administration, (d) axial T2-FLAIR-weighted images, (e) axial diffusion weighted images, and (f) T2∗-weighted images of a 50-year-old woman with headache associated with raised pressure and vertical diplopia revealed a sellar and suprasellar lesion with hemorrhagic areas displacing dorsally the chiasm, thickening the infundibulum and cavernous sinus extension predominantly to the right side. (g) Photomicrograph ×100 H & E and (h) photomicrograph ×400 H & E showed pituitary parenchymal necrosis with blood vessel and group of multinucleated giant cells surrounded by lymphocytes and epithelioid cells.
