Extended endoscopic endonasal approach. Preoperative T1-weighted axial (A) and coronal (B) gadolinium-enhanced MRI demonstrate a right heterogeneously enhancing lesion involving the medial orbit, eroding through the lamina papyracea medially and the anterior skull base superiorly, but respecting the maxillary sinus inferiorly. The lesion compresses the right orbital contents including the optic nerve. The medial location of the lesion and erosion into the ethmoid sinus facilitated an endoscopic endonasal transmaxillary transorbital approach by a multidisciplinary team. Postoperative T1-weighted axial (C) and coronal (D) gadolinium-enhanced MRI demonstrate complete resection of this lesion.
