On contrast-enhanced MRI, the cluster of veins in developmental venous anomalies has a spoke-wheel appearance; the veins are small at the periphery and gradually enlarge as they approach a central draining vein. This appearance has been referred to as caput medusa, or the head of Medusa, because of the serpentine appearance of the curvilinear peripheral draining veins. These are axial and coronal post contrast images of 13 year old girl with hsitory of absence seizures. Reported by- Teleradiology Providers
