Dural arteriovenous fistulae developing at different locations after resolution of previous fistulae: report of three cases and review of the literature.

We present three cases of unusual dural arteriovenous fistulae developing at other dural sinuses after resolution of initial lesions by treatment. In all three cases, the second lesions developed at different sinuses ipsilateral to the initial lesions, and the intervals between the resolution of the initial lesions and the appearance of the second lesions was <12 months. Clinical characteristics, including those previously reported, are discussed.
