Convexity Meningiomas

Abstract

Despite their often benign histology, convexity meningiomas can exhibit a malignant nature through their propensity to recur. The mainstay of convexity meningioma treatment remains aggressive surgical resection even for recurrences. Advances in micro-surgical techniques and intraoperative adjuncts have facilitated the safety and effectiveness of this approach. Careful attention to surgical technique can reduce surgical mortality and limit postoperative morbidity. For lesions that do recur or that are deemed unresectable, consideration is give to radiotherapy. There is no doubt that radiotherapy is a valuable adjunct to surgical resection in patients with tumors demonstrating more malignant features. The risk of radiation therapy must be more cautiously evaluated following resection of benign convexity meningiomas. This article discusses the classification, presentation, and management pertinent to convexity meningiomas.The controversy surrounding adjuvant radiotherapy is also explored as it relates to meningiomas of the convexity.
