Nonenhanced computed tomography (a) and arterial phase of CT (b). Multiple liver tumors are depicted as low attenuation areas in nonenhanced CT and exhibited early enhancement in the arterial phase. These tumors were considered hepatocellular carcinomas.

C virus referred to our hospital for further examination and treatment of multiple hepatic masses. Computed tomography (CT) revealed multiple HCCs in both lobes of the liver (Figures 1(a) and 1(b)).

Nonenhanced computed tomography image. High-attenuation areas were observed in multiple HCCs considered to indicate multiple intratumoral hemorrhages.

CT examination showed high-attenuation areas in the multiple HCCs (Figure 2), and perilesional blood was also observed near the hepatic tumor in the right lobe of the liver (Figure 3).
Nonenhanced computed tomography image. Perilesional blood was also observed near the hepatic tumor in the right lobe of the liver that was considered to indicate rupture of the HCC (arrow).

CT examination showed high-attenuation areas in the multiple HCCs (Figure 2), and perilesional blood was also observed near the hepatic tumor in the right lobe of the liver (Figure 3).
Pooling of contrast medium was observed on angiography (arrow). Right hepatic artery was replaced on the superior mesenteric artery.

CT during hepatic arteriography (CTHA) (Figures 4 and 5). CTHA also demonstrated a decrease in vascularity of the hepatic tumors mainly in the right lobe of the liver which was suggestive of a decrease in the viability of the tumor (Figure 5).
Arterial phase of computed tomography during right hepatic arteriography. Pooling of contrast medium was observed (arrows). Contrast effect of tumors was low (arrowheads) and it was considered to indicate decrease in vascularity of hepatocellular carcinomas.

Arterial phase of computed tomography during left hepatic arteriography. In the left lobe of the liver, tumor stains were observed in more tumors than in the right lobe (arrowhead).
