Engorged veins, however, are often visible through the normal abdominal wall. Engorged veins forming a knot in the area of the umbilicus are described as caput medusae. The extent of associated findings depends on the underlying etiology. It is usually secondary to liver cirrhosis, with subsequent portal hypertension and development of circulation circumventing the liver.
