Patient Data

Age: 50 years
Gender: Male

An arterio-portal shunt is developed between the left hepatic artery and left branch of portal vein and responsible for the patchy abnormal enhancement of the left hepatic lobe. Successful ablation of two hepatic focal lesions with no viable tumoral tissue detected.

Case Discussion

The transient hepatic attenuation difference may occur as a result of portal vein thrombosis or A-V fistula which alter the regional blood supply to the liver. In this case the A-V fistula developed either due to direct infiltration of hepatocellular carcinoma or from radiofrequency ablation.
