Caput Medusa refers to varicose veins radiating from the umbilicus; where are they located?

Explanation:
Caput Medusae reflect collateral veins in the abdominal wall caused by portal hypertension. The characteristic pattern is distended superficial veins that radiate from the umbilicus across the anterior abdominal wall. This occurs because paraumbilical veins reopen and connect the portal venous system to systemic veins around the umbilical area, forcing blood to find alternate routes and dilate the periumbilical network. So, the location is around the umbilicus on the abdominal wall. The other sites listed—ankle, inguinal region, or forehead—do not correspond to this periumbilical collateral pattern and are not where Caput Medusae appear.
