Images of a 56-year-old man presenting with visual disturbance (case 2).

A. The axial unenhanced CT image shows the lesion to be well-defined and hyperdense.

B. The T2-weighted axial MR image (4000/98 [TR/TE]) shows a well-defined 'figure eight' shaped mass that is hypointense to the muscle in the pituitary fossa and it has a suprasellar extension.

C. Photomicrograph shows the prominent collagenous tissue with cellular areas that are composed of haphazardly arranged spindle cells. (hematoxylin-eosin stain, original A B magnification (100))
