Core Tip
Core tip: In 2017, a group of French Researchers proposed a new classification of hepatocellular adenoma based on genomic analysis, identifying three additional subtypes. However, in this latest paper, the possible imaging features of the aforementioned new subtypes of hepatocellular adenoma were not reported. This review analyzed the imaging features of hepatocellular adenoma using magnetic resonance imaging with hepato-specific contrast agents, focusing on the limitations of the “old” imaging criteria proposed by the European Association for the Study of the Liver when applied to the new subtypes of adenoma.
