De Novo Arteriovenous Malformation in a Pediatric Patient: Case Report and Review of the Literature

The exact pathophysiology of de novo AVMs is not completely understood, but a combination of genetic, molecular, and environmental factors may play a role. Our case report only adds to the growing body of clinical evidence supporting the notion that these lesions may be acquired. It would be appropriate to consider an AVM as an abnormal vascular response to an injury rather than a static congenital lesion.
