Core Tip

Core tip: We report the first case of lymphoepithelioma-like cholangiocarcinoma observed using sonography, computed tomography, and magnetic resonance images and delineate the pathologic correlations. According to a review of previous studies, lymphoepithelioma-like cholangiocarcinoma may affect more middle-aged woman. We suggest that the imaging pattern of lymphoepithelioma-like cholangiocarcinoma, either a typical cholangiocarcinoma pattern or a mimic of hepatocellular carcinoma, should be considered in the differential lists for hepatocellular carcinoma.
