A 64-year-old Japanese woman with a history of bronchiectasis presented with multiple hypervascular nodules in both lobes of the liver without hepatitis B or C virus infection. Imaging studies, including ultrasound, contrast-enhanced computed tomography and magnetic resonance imaging, showed hypervascularity in the early phase. Histologically, no lipid degeneration was observed; however, there was a mild increase in cell density, miniaturization of nuclei, increased chromatin content, partial sinusoidal dilatation and congestion. No unpaired arteries were evident. The diagnosis based on the pathology and diagnostic radiology findings was multiple hypervascular focal nodular hyperplasia (FNH)-like lesions with no history of alcohol abuse or chronic liver disease.
