A 67-year-old man presented with consciousness disturbance and righthemiparesis. Computed tomography (CT) scan showed an intracerebral hematomawith two enhanced vascular lesions. Digital subtraction angiography revealedthe dural arteriovenous fistula (dAVF) in the falx cerebri which wassupplied by both bilateral middle meningeal arteries and left pericallosalartery and drained into both the superior sagittal sinus and the vein ofGalen via the posterior callosal vein accompanied by two venous pouches. ThedAVF was obliterated by a combination of the endovascular and the directsurgeries. A dAVF in a falx cerebri is very rare and only five cases werereported. Clinical characteristics of the dAVFs are uncertain. Beforedeciding the strategy of treatment, it is important to consider thepathological condition including embryology of the falx, the falcine sinus,and the falcine venous plexus.
