Convexity meningioma associated with noncontiguous dural arteriovenous fistula

Abstract

Background: Concomitant dural arteriovenous fistulas (DAVFs) and meningiomas have been rarely described. DAVFs can be either continuous or at a distant location from the meningioma, with different pathophysiologic mechanisms involved in each situation. Case Description: We report the case of a 74-year-old woman presenting with left-sided hemiparesis secondary to a large right convexity meningioma, associated with a noncontiguous Borden 3 DAVF. Both lesions were treated surgically in the same setting. The patient improved after surgery, and postoperative imaging showed complete resection of the meningioma and absence of recurrence of the fistula at 4 years. Conclusion: To the best of our knowledge, this is the first case of concomitant surgical treatment of a meningioma and noncontiguous DAVF.
