Abstract
Developmental venous anomalies (DVAs) are the most common vascular malformation of the brain and are commonly identified on routine imaging of the brain. They are typically considered incidental findings, usually with no clinical significance. However the increasing identification of DVAs as a result of improved imaging technology has led to recognition of their association with a variety of abnormal imaging findings and clinically important conditions. This pictorial essay explores the suspected embryological origin, associated imaging features, and proposed pathophysiological mechanisms of DVAs in the pediatric population. This paper emphasizes newer physiological imaging data, which suggest that DVA drainage has less physiological flexibility than otherwise normal venous drainage development.
