Abstract

Developmental venous anomaly (DVA), which is also called venous angioma, is the most common cerebral vascular malformation (1, 2). DVA exhibits radially arranged, dilated veins (so-called caput medusae) that drain into an enlarged transcortical or a subependymal collecting vein (3). DVA is usually asymptomatic and it’s often incidentally found on contrast-enhanced (CE) CT or MR imaging.
