Case 329:   Focal Nodular Hyperplasia (FNH)

Diagnostic Category:

Clinical Presentation:

38 year old woman with 2 year history of intermittent epigastric pain.

CT: In steatosis

Imaging Findings:

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.
