Figure 4. 55-year-old man with ruptured hepatocellular carcinoma during follow-up study. (a) Portal phase CT shows multiple ill defined, low attenuating lesions with solid components in the right and caudate lobe. A nodular high density in the caudate lobe (arrow) represents lipiodol uptake by the lesion during previous transarterial injection. (b) After 17 days, almost all the lesions have become non-enhancing low attenuating, and further low attenuating nodular lesions are now detected (arrows). The non-enhancing low attenuating lesions are larger in area and have more distinct margins than the initial detected lesions (arrowheads). A ruptured mass is not suspected.
