Posterior clinoid meningioma: A case report with discussion on terminology and surgical approach
نویسندگان
چکیده
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.

Endoscopic transnasal suprasellar approach for anterior clinoidal meningioma: A case report and review of the literature
BACKGROUND Anterior clinoidal meningiomas (ACM) are traditionally approached through transcranial routes. Due to their tendency to extend laterally and their proximity to vital neurovascular structures, the endoscopic transnasal suprasellar approach is still questionable. We present and describe an ACM case that underwent an endoscopic transnasal suprasellar approach, and provide a review of th...
متن کاملMultiple Intracranial Aneurysms Concurrent with a Clinoid Meningioma: A Case Report.
The coexistence of intracranial aneurysms and a meningioma is not a clinically common phenomenon. Here we present the case of a meningioma of the left anterior clinoid process concurrent with a right clinoid aneurysm and a ruptured aneurysm of the left post communicating artery (PcomA). Immediately after radiographically establishing a diagnosis of multiple aneurysms and to reduce the risk of r...

متن کاملOssification of Caroticoclinoid Ligament in a Human Skull: A Case Report
The Anterior Clinoid Processe (ACP) and Middle Clinoid Process (MCP) are sometimes connected by an osseous bridge formed by ossification of Carotico-clinoid Ligament (CCL), converting the distal end of carotid sulcus into an ostium called the Carotico-clinoid Foramen (CCF). Through the CCF passes one of the segment of Internal Carotid Artery (ICA). The CCF is the result of ossification of eithe...
متن کاملLateral orbital wall approach to the cavernous sinus.
OBJECT Lesions of the cavernous sinus remain a technical challenge. The most common surgical approaches involve some variation of the standard frontotemporal craniotomy. Here, the authors describe a surgical approach to access the cavernous sinus that involves the removal of the lateral orbital wall. METHODS To achieve exposure of the cavernous sinus, a lateral canthal incision is performed, ...
