Although the pathogenesis of dural arteriovenous fistula (DAVF) remains controversial, a few recent articles have reported in support of the viewpoint that it is an acquired lesion. These include a range of different theories regarding the mechanism of occurrence of acquired DAVF, but few articles have discussed the mechanism of its disappearance in detail. We describe two cases of the disappearance of DAVF of the transverse-sigmoid sinus after removal of the associated tentorial meningioma on the same side, and speculate that the vascular structures surrounding the acquired DAVF that associated the tumor may have contributed to the disappearance of the acquired DAVE However, as it is difficult to assess such structures preoperatively, this speculation must be supported in future with studies of further cases, including diagnostic imaging.
