Scalp Arteriovenous Malformation (Cirsoid Aneurysm) in Adolescence: Report of 2 Cases and Review of the Literature

Scalp arteriovenous malformations, also known as cirsoid aneurysms, are rare lesions that are congenital, traumatic, or postinfectious in nature. These lesions may be found incidentally or owing to signs and symptoms that they produce, such as an enlarging pulsatile mass, headache, tinnitus, or bleeding. These lesions often constitute high-flow arterial blood from the superficial temporal or occipital arteries with venous outflow into extracranial venous structures.
