GARCIA-CONDE, M. et al. Giant arteriovenous malformation of the scalp: Case report. Neurocirugía [online]. 2006, vol.17, n.5, pp.445-449. ISSN 1130-1473.

Arteriovenous malformations (AVM) in the scalp are infrequent vascular lesions. Its clinical presentation varies from annoying and unaesthetic mass of the skin to devastating hemorrhages. Its origin can be congenital or traumatic. The diagnosis of AVM is based on physical examination and confirmed by internal and external carotid angiography. Nowadays the gold standard treatment is the surgical intervention although the endovascular approach is gaining field in order to reduce blood losses as presurgical or like lonely treatment.  A 50 year old woman was admitted with a huge mass in scalp, with subcutaneous enlarged vessels and no other symptoms. A head traumatic antecedent had occurred 12 years before. The angiography evidenced a mottled AVM with blood supplies from the external and internal carotid arteries, with meningeal transosseous branches from both ophthalmic arteries. Endovascular treatment could not be performed due to high risk of uni- or bilateral amaurosis. Thus, a conventional surgical treatment was done without complications. The treatment of AVM of scalp offers various possibilities but the individualization of each case becomes essential to decide the correct management in order to avoid complications.
