Abstract

Focal nodular hyperplasia (FNH) is characterized by the presence a central scar with radiating fibrous septa. Our case had a capsular retraction, which was the result of an extension of the central scar to the surface. In addition, a hypointense scar on the T2-weighted image and a minimal enhancing central scar on the enhanced T1-weighted image, which was due to dense, sclerotic collagenous tissue, were observed. We report the first case of FNH with a capsular retraction.

  Fig. 1 A. 28-year-old woman with focal nodular hyperplasia with a retraction of the liver capsule. On hepatic helical CT scan during the portal phase, the mass shows an iso-attenuation with the liver parenchyma. The mass has a central fibrotic scar (small black arrows), and the liver capsule adjacent to the mass is retracted (large arrow). B. Contrast enhanced T1-weighted MR image reveals that the tumor is well enhanced with a minimally enhancing central scar (small black arrows). The lateral surface of the liver parenchyma adjacent to the mass is retracted (large arrow). C. The hepatic mass of segment 6 is measures approximately 3.5×5.5 cm. The cut surface of the mass reveals a nodular configuration with a central fibrous scar, extending to the liver surface (white arrow). The resected specimen shows a depressed thickened stellate scar (black arrows), slightly eccentrically positioned, with tapering fibrous septa that radiate through the mass, dividing it into multiple lobules.
