Hemangiomas and AVMs are distinct congenital, benign, vascular lesions. Differentiation between the two is important because AVMs are amenable to embolization techniques and because patients with hemangiomas can be told they have a better prognosis than those with AVMs. A major error of management is to ligate the arterial blood supply to an AVM proximally, as the lesion will continue to grow, more collateral vessels will develop, and future angioaccess for purposes of evaluation or embolization will be denied. With care and prudence, many of these lesions can be successfully excised, or at least managed, so that the effect of these sometimes devastating lesions can be ameliorated.
