Abstract
Combined hepatocellular-cholangiocarcinoma (HCC-CC) is a rare tumor showing histological evidence of both hepatocellular and biliary epithelial differentiation. Because of its rarity, there have been few reports about the imaging findings of this tumor. The CT findings of the combined HCC-CC include well-defined tumor with signs of malignancy such as hepatic hypervascularity, biliary obstruction, satellite nodules, and lymphadenopathy. Some portions may show hypoattenuation on arterial phase, whereas other portions show delayed persistent enhancement. The signal intensity of this tumor on magnetic resonance (MR) imaging is not specific. However, when the tumor resembles cholangiocarcinoma on gross pathologic exam, it shows peripheral rim-like enhancement, infiltrative margin, and portal vein invasion in patients with liver cirrhosis. On the other hand, when the tumor has gross appearance of HCC, imaging findings are not helpful for diagnosis. Cross-sectional imagings are helpful for predicting the predominant component of the combined HCC-CC and determining the treatment strategy.
