Figure 17a. Infarct in a 42-year-old woman with fatigue 5 years after liver transplantation. The fatigue was secondary to delayed hepatic artery thrombosis, which led to extensive infarction of the liver. (a) Transverse US image of the liver shows a large area of heterogeneous parenchyma with central hypoechoic areas (arrows), which represent necrosis. (b) Corresponding contrast-enhanced CT image shows the infarct (arrows).
