Multiple focal nodular hyperplasia: atypical imaging characteristics in the setting of hepatic steatosis.

Focal nodular hyperplasia is an uncommon, benign lesion of the liver most often affecting women of childbearing age. It can present clinically with chronic, intermittent right upper quadrant pain and nausea, with associated liver enzyme abnormalities. The presence of characteristic sonographic and computed tomography imaging findings can help to differentiate this entity from other hepatic masses. This article describes an unusual case of multifocal disease that demonstrates atypical imaging findings in the background of hepatic steatosis.
