(a) Fluid-attenuated inversion recovery (b) gado (c) gado magnetic resonance venography images showing filling defects in mid-superior sagittal, R transverse, and sigmoid sinuses. Magnetic resonance imaging done after 16 months (d) T2, (e and f) magnetic resonance venography/magnetic resonance angiography showing nonvisualization of sinuses with markedly tortuous collaterals suggesting a dural arteriovenous fistula. (g and h) Cerebral angiogram confirming dural arteriovenous fistula in superior sagittal sinus with feeders from bilateral superficial temporal, occipital, middle meningeal artery, and right ophthalmic arteries
