Fig. 1 Preoperative and postoperative imaging. Sagittal gadolinium-enhanced T1 preoperative (A) and (B) postoperative images of the endoscopic transtubercular approach for a large retrochiasmatic craniopharyngioma. Preoperative sagittal CISS image (C) and postoperative sagittal gadolinium-enhanced T1 (D) of the posterior transpetrosal approach.

Fig. 2 Intraoperative images. (A) In posterior transpetrosal approach, posterior mobilization of the transverse–sigmoid junction opens up the surgical corridor between the temporal lobe and posterior fossa (white arrows). (B) Initial dissection of the arachnoid of the interpeduncular fossa and exposure of the tumor. Endoscopic assistance allows detailed inspection of the surgical bed (C) and a better appreciation of the surrounding neurovascular anatomy (D). CN, cranial nerve; L optic N, left optic nerve; R optic N, right optic nerve.
