Intrahepatic cholangiocarcinoma most often presents as a mass within the liver that grows and then gradually disrupts bile flow, so jaundice tends to appear later in the course. The tumor starts inside the liver and causes a detectable hepatic mass with nonspecific symptoms like discomfort or weight loss; only as it enlarges does it block intrahepatic bile ducts and lead to cholestasis and jaundice. This pattern differs from obstruction at the distal biliary tree, where jaundice and a palpable gallbladder (Courvoisier sign) are more prominent early on. So a liver mass with jaundice developing later fits intrahepatic cholangiocarcinoma best. Early obstructive jaundice with a palpable gallbladder points more to extrahepatic obstruction, pruritus without jaundice is not typical of ICC, and acute hepatitis-like symptoms are not characteristic of this cancer.
