case_images: Seller MRI scans showed a sellar lesion with suprasellar extension and compression of the optic chiasm. (A, B) The lesion located in the sellar region presented with an isointense signal on T1- and T2-weighted MRI; (C, D) The mass was uniformly enhanced on MRI after contrast enhancement, and a pituitary adenoma was highly suspected. (E-H) The postoperative MRI showed total resection of the lesion.

case_images: A pituitary adenoma was highly suspected ( Figures 1A-D ). And the postoperative MRI showed total resection of the lesion ( Figures 1E-H ).
case_images: Intra-operative conditions of the lesion. (A) The dura of sellar floor was invaded by the tumor; (B) The lesion was soft, mimicking pituitary adenoma in texture (the arrow); (C) The dura of sphenoid platform was opened; (D) The lesion was totally resected and the third ventricle was revealed. a, the invaded dura of the sellar floor; b, the cavernous sinus; c, the optic nerve; d, the sphenoid platform; e, the tumor; f, the arachnoid membrane of sphenoid platform; g, the optic chiasm; h, the mamillary body; i, posterior commissure.
