Abstract
Developmental venous anomaly (DVA) was first considered a rare vascular malformation (1, 2). Nowadays, with the advent of Computed Tomography (CT) and especially Magnetic Resonance Imaging (MRI), DVAs are seen every week to month by radiologists (3, 4). Most DVAs are solitary, asymptomatic lesions and are discovered incidentally, They have a relatively benign nature with a low incidence of hemorrhage. When they do bleed, this is thought to be due to associated vascular malformations, like cavernous angiomas. The typical angiographic appearance of a DVA is a caput medusae appearance in the venous phase. MRI combined with MR angiography (MRA) replaces angiography in most uncomplicated cases as a non-invasive alternative (3, 5).
