Magnetic resonance imaging in evaluating focal liver lesions

Benign liver tumors

From a practical standpoint, the most important benign hepatic tumors are hepatocytic adenoma, focal nodular hyperplasia, cavernous hemangioma, and bile duct hamartoma. The surgeon needs to be familiar with the pathogenesis, gross and radiologic appearance, and natural history of each of these lesions to formulate an appropriate therapeutic plan.
