A special recurrent pattern in small hepatocellular carcinoma after treatment: Bile duct tumor thrombus formation

Figure 1 Small hepatocellular carcinoma in a 35-year-old male. A: T1-weighted magnetic resonance imaging (MRI) shows primary sHCC (arrow) in segment VIII; B: T2-weighted MRI shows an intrahepatic recurrent tumor (arrow) at the margin of the residual cavity following resection of primary sHCC; C: A BDTT (arrows) extending through the intrahepatic bile duct into the common bile duct is depicted in a T2-weighted image; D: Histologically, intrahepatic recurrent tumor and BDTT are moderately differentiated HCC [hematoxylin and eosin (HE), × 100]. sHCC: Small hepatocellular carcinoma; BDTT: Bile duct tumor thrombus; HCC: Hepatocellular carcinoma.
