Introduction
Meningiomas are benign intracranial tumors with a high surgical success rate—especially convexity meningiomas, which are relatively straightforward to resect surgically due to their superficial location; the vast majority can be completely removed. However, some meningiomas—such as those closely associated with the sagittal sinus—may not be amenable to complete resection.
Meningiomas are benign intracranial tumors. The surgical success rate for meningiomas is nearly 100%, especially for those located on the cerebral convexity. Such surgeries are relatively straightforward due to the superficial location of these tumors, and in the vast majority of cases, complete resection is achievable.
If complete surgical resection is achieved without residual tumor, the patient can be considered cured postoperatively. However, in some cases—such as meningiomas closely associated with the sagittal sinus or deeply situated at the skull base where they adhere to critical neurovascular structures—complete resection may not be feasible.
Nonetheless, surgery can still remove the majority of the tumor, and any residual tumor may be treated with Gamma Knife radiosurgery to delay tumor progression and prevent recurrence.
Overall, meningiomas are benign tumors with excellent surgical outcomes and a very high success rate. Therefore, if a meningioma is detected, surgical resection remains advisable—provided the patient is not extremely elderly or in severely poor health—as it offers the prospect of long-term survival.
