The treatment of meningioma primarily involves surgical removal to alleviate symptoms and potentially achieve a cure. In cases where the tumor cannot be completely removed or recurs, radiation therapy may be utilized. Here are the main treatment options for meningiomas: 

1. Surgery (Resection):

• Goal: Achieve complete or partial removal of the meningioma to relieve symptoms and potentially cure the tumor. 

• Procedure: Neurosurgeons perform a craniotomy or use minimally invasive techniques to access and remove the tumor while preserving surrounding healthy brain tissue. 

• Indication: Surgery is generally recommended for symptomatic meningiomas, larger tumors exerting pressure on the brain, or those located in accessible areas where safe removal is possible. 

2. Surgery (Resection):

• Goal: Destroy any remaining tumor cells post-surgery (as adjuvant therapy) or treat meningiomas that cannot be completely excised. 

• Types: 

• External Beam Radiation Therapy (EBRT): High-energy radiation beams are aimed at the tumor from outside the body. 

• Stereotactic Radiosurgery: Precise, focused radiation beams are delivered from multiple angles to target the meningioma while minimizing damage to adjacent tissues. 

• Indication: Employed for residual or recurrent meningiomas, tumors located in critical areas where surgery poses risks, or for patients not suitable for surgical intervention.
