Centrifugal enhancement in a liver lesion is most commonly seen in focal nodular hyperplasia, and this pattern is a good predictor of these lesions at contrast-enhanced ultrasound1. However, centrifugal enhancement can be an atypical feature of liver haemangiomas2 (the more commonly seen pattern in haemangiomas is centripetal).
In this case, centrifugal enhancement can be observed in a lesion as small as 1.4cm. The likely diagnosis is FNH, although the imaging is not diagnostic. There are no features to suggest a malignant process. This patient will be followed up with B-mode ultrasound to ensure stability.
