Caput Medusae Sign

The term caput medusae is also used to described a completely different entity, seen in patients with severe portal hypertension. It describes the appearance of distended and engorged paraumbilical veins, which are seen radiating from the umbilicus across the abdomen to join the systemic veins.

(The caput medusae sign, also refers to developmental venous anomalies of the brain, where a number of veins drain centrally towards a single drain vein. The appearance is reminiscent of Medusa, a gorgon of Greek mythology, who was encountered and defeated by Perseus. The sign is seen on both CT and MRI when contrast is administered. Angiographically the caput medusa appearance is seen only in the venous phase.)
