Abstract:
Falcine meningiomas (FMs) are defined as meningiomas arising from the falx, covered by the overlying brain parenchyma, and not involving the superior sagittal sinus (SSS). FMs together with parasagittal meningiomas represent the second most common location of intracranial meningioma. Clinical presentation depends on the dimensions and location of the FM. Surgery for FM removal deserves several considerations related to bridging veins, anterior cerebral artery branches, arterial feeders, SSS involvement, FM locations, and FM dimensions. In this chapter the principal aspects influencing surgical strategy are analyzed together with approaches and management.
Insights
Falcine meningiomas (FMs) are tumors on the falx cerebri. Surgical strategies for FM removal consider various anatomical factors for optimal patient outcomes.
Area of Science:
- Neurosurgery
- Neuropathology
- Neuroradiology
Background:
- Falcine meningiomas (FMs) are intracranial tumors originating from the falx cerebri.
- They represent a significant portion of meningiomas, second only to parasagittal locations.
- Clinical presentation varies based on tumor size and precise location.
Purpose of the Study:
- To analyze key factors influencing surgical strategies for falcine meningioma (FM) removal.
- To discuss various surgical approaches and management considerations for FMs.
- To provide a comprehensive overview of FM surgical decision-making.
Main Methods:
- Review of surgical considerations for falcine meningiomas.
- Analysis of anatomical factors impacting surgical planning.
- Discussion of different surgical approaches and management techniques.
Main Results:
- Surgical strategy is dictated by FM location, dimensions, and involvement of adjacent structures.
- Consideration of bridging veins, anterior cerebral artery branches, and arterial feeders is crucial.
- Superior sagittal sinus (SSS) involvement significantly influences surgical planning and approach.
Conclusions:
- Effective surgical management of falcine meningiomas requires careful preoperative planning.
- Tailoring the surgical approach to individual tumor characteristics and patient anatomy is essential.
- Understanding the nuances of FM resection leads to improved surgical outcomes.
