title: Focal nodular hyperplasia in a young female.
abstract: A 41-year-old woman, who was taking oral contraceptive drugs, presented with a symptomless hepatic mass lesion shown by abdominal ultrasound. Doppler ultrasound, computed tomography (unenhanced and enhanced with contrast) and magnetic resonance imaging after intravenous gadolinium suggested this was focal nodular hyperplasia. Ultrasound-guided liver biopsy had been performed elsewhere and was also diagnostic. The differential diagnosis of hepatic mass lesion is illustrated and particularly the distinction of focal nodular hyperplasia from adenoma. The importance of radiological imaging techniques is stressed. Clinical management is discussed.
