Spontaneous closure of a type 2a dural arteriovenous fistula following late recanalization of the occluded sinus.
We describe the rare spontaneous resolution of a type 2a dural AVF that coincided with recanalization of the previously thrombosed sigmoid sinus after ten years of conservative management. The factors potentially responsible for spontaneous fistula obliteration are discussed and the therapeutic implication of this observation is considered.
