Background: Scalp arteriovenous malformations, also known as cirsoid aneurysms, are complex collections of directly communicating arteries and veins. As a cirsoid aneurysm grows, it can recruit a blood supply from multiple intracranial and extracranial vessels and involve both scalp and facial tissue. Depending on their size and complexity, a variety of strategies can be used to treat them. Case Description: We have presented the case of a giant cirsoid aneurysm treated with endovascular embolization, resection, and reconstruction using multiple expanded scalp and facial flaps. A 15-year-old boy had presented with a pulsatile left temporal scalp mass that had slowly grown to involve most of his left scalp and extend into the ipsilateral face. At his next presentation, at 19 years old, he had recently developed episodic lateral visual field loss, photophobia, headaches, and vertigo. Catheter angiography demonstrated an extensive arteriovenous malformation supplied primarily by the left superficial temporal, posterior auricular, and occipital arteries, as well as by the ophthalmic artery, The angiogram also showed a dural arteriovenous fistula. Initially, tissue expanders were placed in the vertex, occipital, and left lower facial regions. The patient then underwent endovascular embolization, followed by resection and reconstruction of the tissue defect using multiple expanded scalp and facial flaps. The patient recovered well without neurological deficits and had complete resolution of his symptoms. Our surgical collaboration resulted in overall preservation of his hairline and facial symmetry. Conclusion: Large cirsoid aneurysms can require multidisciplinary treatment combining embolization, resection, and plastic surgical techniques to close the tissue defects.
