Fig. 1 Near-total resection of this tuberculum sellae meningioma was achieved as demonstrated by these pre- and postoperative imaging studies. Notice the enhancement of the right optic nerve preoperatively indicating likely invasion of the optic canal.

Fig. 2 This tuberculum sellae meningioma was near-totally resected through an orbitopterional approach with anterior clinoidectomy. Functionality of the optic apparatus was preserved by microsurgical preservation of the perforators as shown here. ON, optic nerve.
