Results of surgical excision of cirsoid aneurysm of the scalp without preoperative interventions

Cirsoid aneurysms of scalp are rare lesions which are mainly treated by surgical excision. Endovascular embolization was described either alone or prior to surgery in order to minimize the risk of bleeding. However, the endovascular therapy also carries the risk of scalp necrosis, escape of embolization material to circulation, and recurrence of the lesion.
