Fig. 1 (A) Preoperative T2-weighted MRI image showing invasion of the floor of the 3rd ventricle. (B) Sagittal and axial contrasted images showing anterior displacement of the normal pituitary gland. (C) Visual fields preoperatively showed left temporal hemianopia. (D) Intra-operative image showing the foramina of Monroe. (E) Resection of tumor from the retrosellar region revealed the basilar bifurcation and mammillary bodies. (F) The suprasellar region was exposed to allow for superior displacement of the pituitary gland. (G) Postoperative imaging showing complete resection of the lesion.
