(a) A Computed tomography (CT) showed a peripherally enhanced low density mass 7.5 cm in diameter, which located in segment 6 in the right lobe of the liver. (b) Tumor was accompanied with tumor thrombus to the posterior branch of portal vein. (c) Celiac angiography showed this lesion to be hypervascular. (d) Portal vein tumor thrombus in posterior segment was observed in portal phase of SMA angiography.

A Computed tomography (CT) showed a peripherally enhanced low density mass 7.5 cm in diameter, which located in segment 6 in the right lobe of the liver (Figure 1(a)). The tumor was accompanied with tumor thrombus to the posterior branch of portal vein (Figure 1(b)). Celiac angiography showed this lesion was hypervascular (Figure 1(c)) and portal vein tumor thrombus in posterior segment was observed in the portal phase (Figure 1(d)). 
(a) Intraoperative findings revealed tumor was white and intrahepatic metastasis was observed. (b) On cut section, tumor was white and contained coagulation and necrosis. Portal vein tumor thrombus in segment 6 of the liver was observed (arrow heads).

The tumor was white and intrahepatic metastasis was observed (Figure 2(a)). On the cut section, the tumor was white and contained coagulation and necrosis (Figure 2(b)).
(a) Histological findings revealed poorly differentiated HCC with trabecular pattern. Neutrophil infiltration in the tumor was observed. (b) Immunohistochemically, paraffin section of tumor tissue stained positive for IL-8 (arrow heads).

Neutrophil infiltration in the tumor was observed (Figure 3(a)). IL-8 was observed in the cytoplasm of cancer cells (Figure 3(b)).
