Hepatocellular Carcinoma Incidentally Discovered by Liver Abscess Associated with CBD Stone and Cholangitis / 대한간학회지

ABSTRACT

Hepatocellular carcinoma (HCC) is one of the most common fatal malignancies worldwide, especially in Korea. The recent advances in diagnostic techniques, such as serum tumor marker assay, ultrasonography, computerized tomography (CT), magnetic resonance imaging (MRI), and angiography, allow us to detect HCC at early stage. Even though, it remains difficult to distinguish malignant nodules from benign space-ccupying lesions of liver. Distinction of HCC from benign entities such as liver abscess is important because failure of prompt diagnosis could result in a missed opportunity for curative treatment. The differential diagnosis of HCC and liver abscess, especially HCC presenting as abscess, is sometimes very difficult. We report a case of HCC with liver abscess caused by secondary infection of CBD stone and cholangitis, that mimicked the dynamic CT findings of liver abscess, in an elderly patient with chronic hepatitis C virus infection.
