The frequency of hepatic nodular lesion detection has increased due to recent advances in imaging diagnostic
techniques. There are many hypervascular hepatic nodules which need to be differentiated from hepatocellular
carcinoma. Of these lesions, hepatic adenoma, focal nodular hyperplasia, nodular regenerative hyperplasia, and
focal nodular hyperplasia-like nodules will be described in this review article. All of them are hypervascular and
so it is needed to differentiate hepatocellular carcinoma.
