Background. Optic nerve vascular compression in patients with suprasellar tumor is a known entity but is rarely described in the literature.Case Description. We present a unique, well-documented case of optic nerve strangulation by the A1 segment of the anterior cerebral artery in a patient with a tuberculum sellae meningioma. The patient presented with pronounced progressive visual deterioration. Following surgery, there was immediate resolution of her visual deficit.Conclusion. Vascular strangulation of the optic nerve should be considered when facing progressive and/or severe visual field deterioration in patients with tumors proximal to the optic apparatus.

Cerebral Artery Aneurysm

It is not common for an isolated visual symptom to be the first indication of an aneurysm compressing the optic nerve. The compression can lead to blindness, and a recovery from the blindness is rare. We report a female with a left painless optic neuropathy caused by an unruptured anterior cerebral artery aneurysm. The patient had a temporal hemianopic visual field defect, which progressed to blindness in the left eye, while the right visual function was not affected. A coil embolization of the aneurysm completely restored her visual acuity to 20/20. These findings suggest that aneurysmal lesions should be ruled out in case of unilateral optic neuropathy with hemianopic visual field defects and progressive visual loss.

First Case

Abstract A case of a giant aneurysm arising from the anterior cerebral artery and producing a left homonymous hemianopsia is presented. The aneurysm caused lateral compression of the posterior part of the optic chiasm. After preoperative dynamic assessment of the circle of Willis by angiography and by electroencephalographic recording during carotid artery compression, the aneurysm was trapped with microclips on the anterior cerebral artery proximal and distal to it. Visual field examination 6 months postoperatively showed complete visual field recovery. This is the first case of homonymous hemianopsia caused by an angiographically proven giant aneurysm of the ACA. (Neurosurgery 22:560-563, 1988)

A 70-year-old man with progressive visual disturbances, left superior quadrantanopsia, and right-sided papilledema underwent imaging that demonstrated a right internal carotid artery (ICA) terminus aneurysm with third-ventricle mass effect and ipsilateral optic nerve and chiasm compression. We performed a right modified orbitozygomatic craniotomy, with proximal control and dissection of the aneurysm and small perforator arteries. Temporary ICA and anterior cerebral artery (ACA) clips allowed placement of a large curved permanent clip, reconstructing the ICA bifurcation and maintaining adequate patency of the ACA and middle cerebral artery. Complete aneurysm obliteration was confirmed by intraoperative indocyanine green angiography and postoperative CT angiography.The video can be found here: http://youtu.be/5WEEgmA-g2A.

✓ The angiographic and anatomical features of an anomalous communication between the intradural internal carotid artery and the anterior cerebral artery are described. Essential features of the anastomosis include an origin at, or close to, the origin of the ophthalmic artery, a course ventral to the ipsilateral optic nerve and anterior to the optic chiasm, and a termination near the anterior communicating artery. Although rare, the condition should be considered as an entity. The incidence of associated berry aneurysm and other congenital vascular anomalies is high.

Supraorbital Craniotomy

Background: Tuberculum sellae meningiomas have an incidence from 5 to 10% of all intracranial meningiomas[2] and tend to be surgically difficult and challenging tumors given their proximity to important structures such as the internal carotid artery (ICA), anterior cerebral artery (ACA), and optic nerves.[3] Typically, their growth is posteriorly and superiorly oriented, thereby displacing the optic nerves and causing visual dysfunction, which is the primary indication for surgical treatment.[1] The main goals of the treatment are the preservation or restoration of visual abilities and a complete tumor resection.[1] Conventionally, surgical approaches to tuberculum meningiomas involve largely invasive extended bifrontal, interhemispheric, orbitozygomatic, pterional, and subfrontal eyebrow approaches. The supraorbital craniotomy, however, is a minimally invasive transcranial approach that offers a similar surgical corridor to conventional transcranial approaches, using a limited craniotomy and minimal brain retraction that can be used for tumoral and vascular pathologies,[4,5] offering added cosmetic outcomes.[1] We present the case of a patient undergoing a supraorbital transciliary craniotomy with a tuberculum sellae meningioma causing bitemporal hemianopsia. Case Description: A 70-year-old female with chronic headaches and progressive vision loss and visual field deficit for about 1 year. On ophthalmological evaluation, she was able to fixate and follow objects with each eye, light perception was only present in the right eye, and the vision in the left eye was 0.2 decimal units. Her visual fields demonstrated severe campimetric deficits. Her extraocular movements were intact and bilateral pupils were equal, round, and reactive to light. MRI of the brain demonstrated tuberculum sellae meningioma with bilateral optic canal invasion, displacing the chiasm, and extending ≥180° around the medial ICA wall and anterior ACA wall. The patient underwent supraorbital transciliary keyhole approach for total resection of the tumor. Postoperatively, visual acuity and visual field were significantly improved. Conclusion: Performing a supraorbital transciliary keyhole craniotomy for tuberculum sellae meningiomas requires an adequate and meticulous preoperative planning to determine the optimal surgical corridor to the lesion. The use of supraorbital craniotomy is safe with good cosmetic results and potentially lower morbidity allowing for adequate exposure, resection, and release of neurovascular structures.

Abstract OBJECTIVE AND IMPORTANCE: Suprasellar meningiomas typically cause bitemporal hemianopsia by direct compression of the chiasm, its blood supply, or both. We report another mechanism for visual loss in suprasellar meningiomas, whereby compression by the suprajacent vascular complex is the offending agent. CLINICAL PRESENTATION: A 78-year-old woman with a suprasellar meningioma was diagnosed incidentally. During the follow-up period, she developed an inferior homonymous wedge defect consistent with superior compression, without any detectable radiological progression. It was decided to resect her tumor. INTERVENTION: The patient underwent a fronto-orbital approach for tumoral excision. Intraoperatively, a groove by the anterior cerebral artery complex was found along the superior surface of the chiasm. Postoperatively, the patient's visual deficit resolved. CONCLUSION: This case illustrates an unusual visual field deficit associated with a suprasellar meningioma. It also emphasizes the importance of frequent and careful visual field monitoring, which can precede radiological and symptomatic progression.

AbstractCompared with traditional craniotomy, the expanded endoscopic endonasal approach (EEEA) may have some advantages for tuberculum sellae meningioma (TSM) treatment. We described our experience of the therapeutic effect of endoscopic TSM treatment. From August 2015 to December 2019, 40 patients with a TSM were treated by the EEEA in our institution. EEEA outcome in TSM treatment was analyzed. Among 39 patients with visual impairment, 38 (97.4%) improved their visual function to some extent after the EEEA, and one case had no significant change in visual acuity. Among all patients, 38 (95.0%) achieved gross total resection (GTR) and 2 (5.0%) achieved near-total resection (NTR). Cerebrospinal fluid (CSF) leakage occurred in three patients (7.5%) and meningitis (post-CSF leakage) in two patients (5.0%). Eight patients (20.0%) suffered postoperative hyposmia, three of whom developed long-term hyposmia. One patient (2.5%) suffered from bleeding of the branch of the anterior cerebral artery intraoperatively leading to postoperative acute cerebral infarction. The EEEA is a safe and reliable minimally invasive method for TSM removal. Compared with traditional craniotomy, the EEEA may have better visual outcomes and a higher prevalence of GTR, but carries the risk of CSF leakage.
