Case 329: Focal Nodular Hyperplasia (FNH)
38 year old woman with 2 year history of intermittent epigastric pain.
CT: In steatosis
CT demonstrates a hypervascular FNH in segment 2/3. It appears mildly hyperdense on all other phases contrary to the usual appearance of FNH, where it usually becomes isodense on portal venous and equilibrium phase in a non-steatotic liver. In a steatotic liver however the non-steatotic FNH remains hyperdense in relation to the hepatic parenchyma in all contrast phases.
