Abstract

Focal nodular hyperplasia-like nodules (FNH-like nodules) are hypervascular lesions that occur in the cirrhotic liver. Histologically, they are similar to classical FNH in an otherwise normal liver. Radiologically, FNH-like nodules may mimic hepatocellular carcinoma (HCC), and they have been misdiagnosed as HCC based on radiological findings. Their pathogenesis and etiology are unclear, but they may arise from a local hyperplastic response to vascular alterations like classical FNH. Rarely, these nodules transform into malignant tumors and cause complications. We report the case of a 28-year-old man with multiple FNH-like nodules in congenital liver cirrhosis.
