Case 58: Focal Nodular Hyperplasia (FNH)
35 year old women with incidental finding in the liver.
CT: Typical, with feeding arteries
CT shows exophytic FNH in segment 6. Typical homogeneously hypervascular enhancement and large central scar. Note two dominant feeding arteries, the medial one (arrows) leading to the central scar. Anteriorly is a thin pseudocapsule (arrowheads), which is often seen in FNH. The pseudocapsule in FNH is often thinner than in HCC.
