Anterior clinoidal meningiomas: functional outcome after microsurgical resection in a consecutive series of 106 patients

Abstract

Acceptable functional results can be achieved after microsurgical resection of ACP meningiomas; however, long-term treatment remains challenging due to a high tumor recurrence and progression rate.

Large medial sphenoid wing meningiomas: long-term outcome and correlation with tumor size after microsurgical treatment in 127 consecutive cases

“…Although the visual outcome had seen some progress in recent years, the overall outcomes remains unsatisfactory (5,6,11,19 (29). In our series, the tumor extending into optic nerve canal was encountered in 10 cases, and the tumor can be pulled out in 9 and only in 1 case the tumor infiltrated the optic canal or optic nerve and needed optic canal opening.…”

“…Al-Mefty(2-4) reported authors (6,9,30-32) proposed a radical and aggressive resection whereas, some authors (5,13,20,21,23,28,35) proposed a conservative strategy with or without following radiosurgery. In our series, total removal was achieved in 104 cases (81.2%), and of 60 cases with CS involvement, 47 were achieved total removal.…”

“…It was known that the more aggressive radical resection is achieved, the higher incidence of morbidity and or even mortality would be led to. However, tumor recurrence, which correlates with the extent of resection, is the greatest threat in long-term outcomes (5,18,27). Therefore, it still puzzles neurosurgeons about how to balance the immediate risk of morbidity or even mortality and long-term risk of tumor recurrence.…”

“…They are still reported to have the worst neurological functional outcome hindering postoperative quality of life (next to petroclival meningiomas) with highest recurrence rate (2,8,18), partly because of their intricate and intimate relationship with cavernous sinus (CS), arteries of anterior circulation, and optic pathways. As radiosurgery plays an increasing important role in benign tumors, there is much controversy about the indications for aggressive resection of MSWM 1,5,13,20 . It was known that the more aggressive radical resection is achieved, the higher incidence of morbidity and or even mortality would be led to.…”

Can 3T MR Angiography Replace DSA for the Identification of Arteries Feeding Intracranial Meningiomas?

“…For the selection of the optimal surgical approach to meningiomas, the precise anatomic location of the dural attachment must be understood, and the critical feeding arteries must be localized early. 3,4 Intra-arterial DSA, the reference standard for assessing the vasculature of meningiomas, plays a role in planning the embolization of large tumors and tumors whose blood supply is inaccessible (eg, those of the base of the skull). 5 The inherently high spatial and temporal resolution of DSA facilitates the identification of the feeding arteries and tumor vascularity.…”
