Patient 3 is a woman. (a, b) Sagittal and coronal views on MRI. The solid mass is in the saddle and suprasellar area, and the suprasellar apart appears lobulated. The tumor shows uneven enhancement. The optic chiasm is elevated and the pituitary is compressed by the mass. The area surrounded by the red dotted line is the area where the tumor is located. (c) Postoperative pathology, tumor cells diffuse in a patchy distribution, local distribution around the sinusoids, cell morphology more consistent with nuclear deep staining, cytoplasmic dichromatic and part of the cytoplasm staining red. (d) After removal of the saddle floor bone, we can see the boundary between the saddle and suprasellar area. (e) A soft tumor is observed under the microscope during surgery. (f) An image of the surgical area after removal of the tumor. The surrounding important adjacent structures are not damaged
