Large Hemangiopericytoma Associated With Arteriovenous Malformations and Dural Arteriovenous Fistulae
Background: Hemangiopericytomas are rare vascular tumors of the central nervous system. Although hemangiopericytomas have been associated with other vascular malformations, there is no report of an intracranial hemangiopericytoma found in association with multiple arteriovenous malformations and dural arteriovenous fistulae. Case Description: We present the case of an otherwise healthy 25-year-old woman who presented with a large hemangiopericytoma involving the superior sagittal sinus. The highly vascular nature of the lesion, the total occlusion of the sinus anterior to the tumor, and the presence of multiple arteriovenous malformations and dural arteriovenous fistulae complicated resection of this tumor. Conclusion: To our knowledge, no prior report has described a tumor of this magnitude in association with multiple AVMs and dAVFs. Â© 2011 Elsevier Inc. All Rights Reserved.
