Arterial embolization as a pre-operative strategy to reduce bleeding in giant meningioma resection

Meningiomas account for 39.7% of primary intracranial tumors, with atypical types comprising 17.7%.Here, we report a case of a 55-year-old woman with a giant right frontoparietal atypical meningioma, for which initial surgery was postponed due to excessive bleeding.Pre-operative endovascular embolization effectively reduced arterial flow to the tumor, allowing for successful complete resection.Histopathological analysis confirmed the atypical meningioma diagnosis according to the World Health Organization criteria.The post-operative course was favorable, with no complications or early recurrence.The objective of this article is to highlight the usefulness of pre-operative embolization in reducing intraoperative bleeding, which helps optimize complete resection, thereby lowering morbidity and the risk of recurrence, as demonstrated in this case.
