title: Focal nodular hyperplasia: report of an unusual case and review of the literature.
abstract: Focal nodular hyperplasia (FNH) is the second most common benign lesion of the liver and a common differential in the workup of solid liver lesions. With increasing use of modern imaging modalities FNH is becoming clinically more relevant. We present a case of pedunculated FNH presenting as a pericholecystic mass. This was resected laparoscopically due to persistent symptoms and uncertainty in diagnosis. We summarize the current literature with regard to the diagnosis, etiology, and management of FNH lesions.
