An Unusual Case of Intrahepatic Stone Masquerading as Cholangiocarcinoma

Year: 2025

Type: article

Abstract: A cancer of the biliary tree, cholangiocarcinoma (CCA) often presents with painless jaundice, right upper quadrant abdominal pain, and unintended weight loss. Serologic testing to include cancer antigen 19-9 (CA 19-9) is elevated in CCA but can also be elevated in inflammatory processes in the biliary system. Diagnosis is difficult and even with advanced imaging techniques false-positives may occur. We present a case of a patient with elevated CA 19-9 and biliary stricture concerning for CCA but was due to hepatic stone. It demonstrates the challenge of correctly diagnosing CCA and an instance of nonmalignant elevation of CA 19-9.
