Laparoscopic resection of focal nodular hyperplasia.

Focal nodular hyperplasia (FNH) is a benign liver lesion incidentally discovered with increasing frequency because of the proliferation of imaging studies. Radiographic characterization can diagnose this pathologic lesion and nonoperative therapy is the standard of care. However, if radiographic studies and fine needle biopsy are inconclusive, operative intervention may be required. Depending on the anatomic location of the lesion, biopsy and/or resection can be performed laparoscopically. A patient with biliary dyskinesia and focal nodular hyperplasia is presented. She underwent laparoscopic cholecystectomy with excision of the FNH. This paper reviews the case as well as the diagnosis and treatment of FNH.
