Abstract
The classical definition of stereotactic radiosurgery (SRS) involves administering a high dose of radiation within a limited treatment area. More recently, it has also encompassed the concept of hypofractionated radiosurgery, which involves delivering radiation over up to five treatment sessions. Intracranial meningiomas (IM) are commonly encountered primary brain tumors. Currently, there has been a rise in the number of asymptomatic individuals with IM, who subsequently require treatment due to the development and onset of symptoms. Small and medium-sized IM treatment standard options encompass radical surgery; however, this may not always be feasible due to surgical risks and patient preferences. In contrast, SRS stands out as an effective tool for managing tumor growth and alleviating symptoms. It is an outpatient procedure that eliminates the need for general anesthesia and extensive postoperative care. This holds particular significance in countries with long surgical waitlists, providing a cost-effective and low complication alternative. Furthermore, SRS plays a crucial role not only in grade I IM but also in addressing some cases of recurrent and residual grade II and even grade III IM. It also has a place in the management of radiation-induced meningioma.
