Summary
Surgical removal of intracranial meningiomas is often possible, but high-risk locations near critical structures limit complete resection. Radiotherapy is an alternative when surgery is not fully curative.
Area of Science:
- Neurosurgery
- Oncology
Context:
- Intracranial meningiomas are common primary tumors of the central nervous system.
- Surgical resection is the primary treatment modality for symptomatic meningiomas.
Purpose:
- To review surgical outcomes and define limits of operability for intracranial meningiomas.
- To identify meningioma subtypes where radical surgery carries high morbidity risks.
Summary:
- Radical surgical removal is feasible for convexity, parasagittal, and anterior basal meningiomas.
- Total resection is challenging and may be contraindicated for sphenoid ridge, petrous bone, and falco-tentorial meningiomas.
- Surgery may be unnecessary for asymptomatic cases or ineffective for cavernous sinus meningiomas, with radiotherapy considered as an alternative.
Impact:
- This review helps define surgical indications and limitations for intracranial meningiomas.
- It guides treatment decisions, balancing the risks of surgery against potential benefits and considering alternative therapies like radiotherapy.
