Brain MRI W/WO contrast 2 days before surgery. (a) Coronal T1-weighted image demonstrates a large sellar mass with suprasellar extension and slight mass effect on the optic chiasm. This mass exhibits marked hyperintense signal on T1-weighted image (arrow), which indicates blood products and recent hemorrhage. (b) Coronal T1-weighted postcontrast image shows normal enhancement of the cavernous sinus. No enhancing mass or nodule is evident in association with intrinsically T1 bright lesion. The mass abuts approximately 90 degrees of the right internal carotid artery contour. This abutment is less on the left side. The carotid arteries are patent and show normal caliber without any narrowing. No normal pituitary tissue is identified.

Brain magnetic resonance imaging (MRI) showed a sellar mass, and the pituitary MRI (Figure 1) revealed a large pituitary mass with extension to the right cavernous sinus.
MRI (T1 weighted with contrast) one day after the surgery shows interval resection of the previously seen sellar mass/hemorrhage and resolution of mass effect on the optic chiasm.

Post-op MRI showed postsurgical changes with no definite residue and no acute complication (Figure 2).
