Caput medusae – a clinical and radiological sign seen in severe portal hypertension. It describes distended and engorged paraumbilical veins radiating from the umbilicus across the abdominal wall to join systemic veins creating portal-systemic anastomoses. The appearance is reminiscent of Medusa, a gorgon of Greek mythology, who was encountered and defeated by Perseus. Pictured is ‘Medusa’ by Caravaggio painted in 1595.
