Superior sagittal sinus dural arteriovenous fistula with changes in angiographic findings associated with contiguous parasagittal meningioma: A case report.

ABSTRACT:

Background

Meningioma and dural arteriovenous fistula (dAVF) located at the same site are rare. The present case demonstrated the transformation of tumor feeding vessels into the pial feeder of the dAVF over time, which may help to elucidate the pathogenesis of tumor-associated dAVF.

Case description

A 71-year-old man presented with convulsion. Magnetic resonance (MR) imaging showed a right parasagittal sinus meningioma invading the superior sagittal sinus (SSS). Bilateral external carotid angiography showed dAVF at the SSS, near the site of tumor invasion. The right internal carotid angiography showed tumor staining from the anterior cerebral artery with intra-tumor arteriovenous shunting, with stagnation of tumor blood flow, suggesting impairment of perfusion to the SSS.
