Figure 2. 69-year-old man with ruptured hepatocellular carcinoma (HCC) during follow-up study. (a) Delayed phase CT shows a large mass with protruding contour in the right hepatic dome. Marginal disruption is suspected (arrows). Definite signs of HCC rupture were not found on physical examination. (b) 6 days later, CT was repeated because of abdominal distention with abdominal pain. Tumour rupture into the intraperitoneal space is seen on portal phase CT. Markedly decreased attenuation is noted within the lesion.
