Fig. 1 Pre- and postoperative magnetic resonance imaging. Preoperative (A) and postoperative (C) Axial T1-weighted magnetic resonance images. Coronal T2-weighted preoperative (B) and coronal T1-weighted postoperative imaging. Gross total resection was achieved.

Fig. 2 Intraoperative pictures. (A) Early optic nerve decompression and improved intracanalicular exposure of the tumor was accomplished by drilling the limbus sphenoidale and medial optic canal. (B) Direct dissection of the tumor was possible, with identification and preservation of the ophthalmic artery (black arrow). (C) Endoscopic view inside the inferomedial optic canal. (D) The use of the 30-degree angled endoscope allowed identification of an area of invaded dura mater (white arrow), which could be coagulated. ICA; internal carotid artery; Left A1, left anterior cerebral artery; Opht.A, ophthalmic artery; optic N, optic nerve.
