Focal nodular hyperplasia


This is a classic case of FNH on US & MRI. It shows a central scar, which is seen in over 60 % of FNH > 3 cm diameter. When present, the central scar enhances on the delayed images in more than 80 % of cases. FNH is a benign liver mass and thus treated conservatively. There is no risk of malignant transformation and a very low risk of bleeding.
