mass in the clivus with moderate enhancement and peripheral
calcifications.
Fig.2 (A, B, C, D): Endoscopic images of transsphenoidal surgery showing
the neoplastic mass adjacent to the intact pituitary gland (A), the
neoplastic mass adjacent to both the right and left ICAs (B, C), and the
pituitary gland after complete resection of the mass (D).
Fig.3 (A, B, C, D, E, F): Histological images of the resected mass
showing small nests of uniform small oval-to-polygonal-shaped cells
surrounded by dense hyaline stroma (A, B), negative staining for
synaptophysin, chromogranin, and CD56 respectively (C, D, E), positive
staining for prolactin (F).
