Figure 7: (a) Preoperative MRI axial cut of spheno-orbital meningioma encroaching upon the lateral aspect of the superior orbital fissure and orbital apex. (b) postoperative MRI coronal cuts showing complete removal of the lesion. (c) intraoperative exposure of the meningo-orbital band in the pterional middle cranial fossa approach. 1: orbitotomy, 2: MOB, 3: temporal dura, 4: frontal dura, 5: base of the anterior clinoid
