CT appearance of “caput medusae” on axial, contrast-enhanced CT scan on portal venous phase in two cirrhotic patients, as a result of the recanalization of the umbilical vein due to portal hypertension. This appearance is due to tortuous vessels (arrows) reaching the abdominal wall at the level of the navel.
