## Abstract

Cirsoid aneurysms, formerly identified as arteriovenous malformations (AVMs), represent infrequent vascular anomalies primarily localized within the scalp. These anomalies are typified by the absence of interposing capillaries, giving rise to extensively vascularized, expanded conduits connecting arterial feeders and venous outflows. This report details a case of a 13-year-old male afflicted with a cirsoid aneurysm in the scalp, who presented with swelling on the left frontal region, accompanied by headache and pulsatile sensations. Definitive diagnosis was achieved through radiological and histopathological examinations. Scalp cirsoid aneurysms may either be congenital in nature or arise following traumatic incidents, with clinical manifestations typically surfacing in the third decade of life. Common clinical presentations encompass a palpable, pulsatile subcutaneous mass, throbbing headaches, tinnitus, and cosmetic concerns. Diverse therapeutic strategies, including surgical excision, endovascular embolization, and percutaneous injection of sclerosing agents, can be employed contingent upon the particular characteristics of the lesion.
