Long-term complete remission of large hepatocellular adenoma after bariatric surgery

We report the case of an obese woman with a large hepatocellular adenoma (HCA) of 8.0 cm in diameter, followed for 5 years after Roux-en-Y Gastric Bypass, with a complete radiologic remission of the liver mass. Four other cases have been published with HCA regression after bariatric surgery, but none with long-term follow-up. As the association between obesity and HCA has been increasingly described, bariatric surgery should be considered a therapeutic option for stage 2 obese patients.
