Abstract

A 72-year-old male patient with visual disturbance of the right eye was diagnosed with a small meningioma of the right optic foramen extending to the carotid cistern. The operation was performed through an individually tailored frontolateral minicraniotomy via a curvilinear skin incision behind the hairline. Endoscope-assisted microsurgical technique was used to resect the lesion. The roof of the optic canal was partly removed to get access to the intraforaminal tumor parts. The lesion could be completely removed and the patient showed a satisfactory visual recovery in the follow-up examinations.

Fig. 1 (A, B) Preoperative contrast agent-enhanced MRI scans of the head revealed a small lesion of the right optic foramen just medially to the anterior clinoid process (red arrows). (C, D) Postoperative contrast agent-enhanced MRI scans of the head show complete tumor removal (red arrows). MRI, magnetic resonance imaging.

Fig. 2 (A) Schematic representation of the supraoptic tumor parts and their relations to the surrounding neurovascular structures. (B) Schematic drawing of the intracanalicular tumor parts within the right optic canal after partial decompression. The surrounding neurovascular structures, such as the optic nerve, ophthalmic artery, and the anterior clionid process, are visible in relation to the tumor. (C) Intraoperative image through the operating microscope. Through the subfrontal approach, the supraoptic tumor parts are visible. (D) Endoscopic image through a 30-degree optic directed to the frontal base after decompression of the right optic nerve and complete tumor removal. ACP, anterior clinoid process; FB, frontal base; ICA, internal carotid artery; M1, middle cerebral artery; NI, olfactory nerve; NII, optic nerve; OC, optic canal; Tu, tumour.
