Hepatocellular carcinoma is the most common primary neoplasm of the liver that typically occurs in the setting of chronic liver disease. In this case report, we present an atypical case of well-differentiated hepatocellular carcinoma, which was detected in a 43-year-old man with no known symptoms of liver disease. We review the imaging features of the mass, which did not follow typical enhancement characteristics defined by the Liver Imaging Reporting and Data System criteria. The diagnosis was ultimately confirmed by histologic analysis of a surgically resected specimen.
