Two consecutive dural arteriovenous fistulae in a child: a case report of successful treatment with gamma knife radiosurgery.

Introduction: The occurrence of dural arteriovenous fistulae in children is quite rare. Endovascular embolization is typically the first line treatment. In general, Gamma Knife radiosurgery is used as adjuvant treatment and seldom performed as the first line treatment in children.

Discussion: We report a case of a 27-month-old girl who presented with an initial dural arteriovenous fistula (AVF) located at anterior base of the left middle cranial fossa. She subsequently developed another dural AVF over the left transverse-sigmoid sinus region 2 years later.

Conclusion: Both fistulae were successfully obliterated with Gamma Knife radiosurgery.
