We report a case of focal nodular hyperplasia in an adolescent with a spontaneous intrahepatic portosystemic venous shunt. Diagnosis was established by duplex and color Doppler ultrasound, computed tomography, magnetic resonance imaging, and histology. This association further supports the hypothesis that focal nodular hyperplasia is a response to a preexisting vascular abnormality.
