A patient with hepatocellular carcinoma(a-f). HBDTT (white arrow heads) show isoattenuation in plain CT image (a), heterogeneous enhancement with relative hyperattenuation in arterial phase (b) and hypoattenuation in portal venous phase(c), without bile duct wall thickening. The spleen is about eight rib elements (a-c). d There is a vascular tumor thrombus (white arrow) in the middle hepatic vein, which is hypoattenuation in portal venous phase. e A coronal image shows the relation between the intrahepatic hepatocellular carcinoma lesion (black arrow) and HBDTT (white arrow head). Diffused intrahepatic biliary dilation could be found (a-d). f (HE stain, original magnification× 200) The HCC is moderately differentiated trabecular type, grade II
