Hepatocellular carcinoma-CT
Chronic alcoholic: liver is shrunken with cirrhotic texture and prominent caudate lobe.Rounded focal lesion is seen in the hepatic dome. The lesion is inconspicuous in the pre-contrast scan showing same density of the liver parenchyma, with enhancement in the arterial phase and becomes isoattenuating in the venous and delayed phases.
Teaching Points
- Hepatocellular carcinoma receives most of its blood supply from the hepatic artery
- Enhancement pattern is the key to correct assessment of HCCs. Usually the mass enhances vividly during late arterial (~35 seconds) and then washes out, becoming indistinct or hypoattenuating in the portal venous phase, compared to the rest of the liver.
- Hepatocellular carcinomas can have a variety of appearances: including focal, mutiple and diffuse
