Benign hepatic neoplasms constitute a heterogeneous group of neoplasms with characteristic histology and variable tumor biology. Based on the cell of origin, benign hepatic neoplasms are classified into epithelial, nonepithelial, and miscellaneous categories according to the 2000 World Health Organization classification system. Benign hepatic neoplasms demonstrate a wide spectrum of imaging findings that reflect the histomorphologic changes. Some neoplasms show pathognomic imaging findings that permit accurate characterization and optimal management.
