Introduction: Focal nodular hyperplasia and hepatocellular adenoma are benign hepatic tumors and differential diagnosis is important as hepatic adenomas may complicate with hemorrhage and malignant transformation. Magnetic resonance imaging with gadolinium-enhanced contrast agents is the best noninvasive diagnostic tool for benign hepatic tumors. Nevertheless, atypical radiological findings can make differential diagnosis a challenge. Presentation of case: We report a young female patient with large hepatic benign tumor with intralesional hemorrhage that disclosed hyper-intensity on hepatobiliary phase on a gadolinium-enhanced magnetic resonance imaging study, suggestive of focal nodular hyperplasia. As this type of tumor usually do not complicate with bleeding, surgical resection was proposed and a laparoscopic right posterior hepatic sectionectomy with selective hepatic artery clamping was performed. Pathology disclosed an inflammatory hepatic adenoma. Discussion: Hepatic adenomas may present as hyper-intense tumors on hepatobiliary phase of gadoliniumenhanced magnetic resonance imaging. Surgical resection still has a role on the treatment of benign hepatic tumors. Laparoscopic liver resections must be considered, even when a major hepatectomy is planned, as this approach has proved safe and effective. Selective hepatic artery clamping during minimally invasive liver surgery may be an option to reduce intraoperative bleeding, remnant liver ischemia and postoperative hepatic failure. Conclusion: We reported a young female patient with a benign hepatic tumor complicated with hemorrhage suggestive of a focal nodular hyperplasia on gadolinium-enhanced magnetic resonance imaging study. A laparoscopic hepatectomy was performed and final pathology disclosed an inflammatory hepatocellular adenoma.
