Computed tomography angiography. (A) The image illustrates a huge mass measuring about 30 cm in the maximum diameter. The left hepatic vein (black arrow) is compressed to the right by the huge mass. In the second hepatic portal, the inferior vena cava (white arrow) is also compressed. (B) The portal vein (black arrow) and superior mesenteric vein (red arrow) are compressed to the right. The trace of the splenic vein (white arrow) is not clear. (C) The superior mesenteric vein (black arrow) is compressed. (D) The tumor is supplied mainly by branches from the left (red arrow) and right gastric artery, although origin from the common hepatic artery is also possible. The common hepatic artery (blue arrow), left hepatic artery and splenic artery (white arrow) are adjacent to the tumor. (E) In addition to the arteries mentioned in (C), the superior mesenteric artery (black arrow) and left renal artery are also next to the tumor and compressed.
