We report two men with left frontoparietal lesions supplied by the frontal branch of the superficial temporal artery. A 37\u2010year\u2010old man presented with a progressively enlarging pulsatile mass of 3 years\u2019 duration. Duplex ultrasonography and computed tomography angiography (CTA) demonstrated a high\u2010flow scalp AVM with extensive venous drainage and no intracranial communication. A 27\u2010year\u2010old man presented with a 1\u2010year history of a pulsatile mass that underwent rapid enlargement, ulceration, and massive bleeding. Temporary hemostasis was achieved by compression, and CTA showed a similar lesion without intracranial communication. Both patients underwent complete surgical excision through a left coronal incision without preoperative embolization. The feeding artery was ligated, the abnormal venous network was resected, and the ulcerated skin was excised in the second patient. Neither procedure required transfusion, and both postoperative courses were uneventful. At clinical follow\u2010up of 6 months in the first patient and 3 months in the second, facial muscle function was preserved, cosmetic outcomes were satisfactory, and no clinical recurrence was detected. These cases support surgical excision as an effective option for localized, surgically accessible CAs with a limited arterial supply, while treatment should be individualized according to lesion extent, vascular anatomy, symptoms, hemorrhagic risk, and cosmetic objectives.<\/jats:p>","DOI":"10.1155\/cris\/9907175","type":"journal-article","created":{"date-parts":[[2026,10,7]],"date-time":"2026-10-07T11:51:53Z","timestamp":1791373913000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Cirsoid
