Vascular anomalies: A pictorial review of nomenclature, diagnosis and treatment

Figure 12 Superficial lesions may present as a warm painless mass with palpable bruit and associated dilated veins. High flow arteriovenous malformation with extensive skin breakdown in the region of this superficial malformation (A). Magnetic resonance angiogram demonstrates a high flow arteriovenous malformation with arteriovenous shunting (arrow) (B). Left internal iliac arteriogram demonstrating filling of the nidus of the malformation (arrow) (C). Arteriography following alcohol embolization shows eradication of the nidus of the malformation (D). As the malformation was located in subcutaneous fat, it was resected en block and skin grafts were created to bridge the area of skin breakdown.
