“…These include dorsum sellae or upper clival meningiomas, retrosellar meningiomas, and PCP meningiomas. [ 1 2 3 4 ] Geng et al . further subdivided the dorsum sellae meningiomas into two groups – type 1 (dorsum sellae, inferior third ventricular type) and type 2 (dorsum sellae, third ventricular type), depending upon the site and direction of growth.…”

“…[ 4 ] These tumors are often referred to as “dorsum sellae” or “upper clival” meningiomas. [ 1 2 3 4 ] Surgical excision of these tumors is challenging owing to their proximity to important neurovascular structures, including optic chiasm, internal carotid artery (ICA), pituitary stalk, and oculomotor nerve. Various surgical approaches have been described to approach the PCP to minimize complications, and to improve the extent of resection.…”

Background:Posterior clinoid process (PCP) meningiomas are rare lesions. In close proximity to these lesions are the perforators from internal carotid artery and the oculomotor nerve, which need to be considered while deciding the appropriate surgical approach.Case Description:We describe a basal frontotemporo-orbito-zygomatic approach with splitting of the sylvian fissure to resect an eccentrically placed PCP meningioma.Conclusion:A basal frontotemporo-orbito-zygomatic approach with splitting of the sylvian fissure is a safe approach to resect an eccentrically placed PCP meningioma.

Clinical and radiological features or characteristics of posterior clinoid process (PCP) meningiomas have rarely been described because of their extreme scarcity and terminological confusion. Therefore, the strategies in the surgical intervention for PCP meningiomas have not been well established. Moreover, the presence of deep and critical neuroanatomical structures and relatively high morbidity, which can be difficult to predict preoperatively, make their surgical excision more challenging. We report two surgical cases of PCP meningioma and discuss the appropriate assessment of preoperative features and surgical strategies with review of the literature. Our study suggests that PCP meningioma may be characterized by the anterior displacement of internal carotid artery, and infero-laterally shifted posterior communicating arteries, and homonymous hemianopsia, a distinctive clinical feature. One of the key issues in PCP meningioma surgery is preservation of the optic nerve. Unlocking the optic nerve by anterior clinoidectomy and dissection, the falciform ligament is the important step to preserve vision for larger tumors. Complication with the perforators is also hazardous of these challenging surgeries than anterior clinoid meningiomas for their specific neuroanatomical structures and might not be feasible to avoid even with additional techniques and critical monitoring. A combination and multi-staged-surgical approach can be options of tailor-made surgical strategy in cases with tumor adhesion to the perforators.
