Case 3

This is an MRI liver study, showing multiple, well defined focal hepatic lesions scattered throughout both lobes of the liver – they appear slightly hyperintense on T2 compared to normal liver parenchyma.

The lesions are slightly hyper-enhancing on the portal venous phase post contrast series, and show greater retention of contrast on the delayed series. The lesions show greater retention of the hepatocyte specific contrast agent on the hepato-biliary phase than background liver parenchyma; they also show non-enhancement of the central area, which represents the fibrous scar. This indicates that the lesions contain functioning hepatocytes.

The findings are characteristic of focal nodular hyperplasia.

I would contact the referring physician and inform of the findings. No further management is required.
