Scalp Cirsoid Aneurysm: An Updated Systematic Literature Review and an Illustrative Case Report

Scalp cirsoid aneurysm is an arteriovenous fistula of the scalp that is unconnected by intracranial or cerebral vessels. Variceal dilatation of draining veins can produce cosmetic concerns, masses, local pain, palpable thrills, and audible bruits, headache, tinnitus, and hemorrhage. Its etiopathogenesis is not well understood. Treatment includes surgery (fistula repair by simple surgical ligation until gross total resection), embolization (whether percutaneous or endovascular), or a combination of the two. An updated systematic review of the last 10 years publications was performed. Also, we report an illustrative case of a young boy with posttraumatic cirsoid aneurysm and good documentation on head vascular examinations, treated by multiple routes (percutaneous embolization with coils and endovascular embolization with cyanoacrylate) with a decrease of the pulsatile mass. A plastic surgery team performed gross total resection, and the final esthetic result was extremely satisfactory.
