title: Benign focal lesions of the liver.
abstract: This article focuses on the origin, diagnosis, and management of focal benign lesions of the liver. The most common lesions include cavernous hemangioma, focal nodular hyperplasia, hepatic adenoma, and nodular regenerative hyperplasia. A number of less frequent occurring lesions are also discussed. In general, the common lesions can be diagnosed by radiologic imaging, but occasionally biopsies are required, and surgical removal is often needed.
