we report two cases of focal nodular hyperplasia in patients following gadoxetic acid (gd-eob-dtpa)-enhanced magnetic resonance imaging confirmed with histopathology. these cases showed an atypical pattern during the delayed-hepatobiliary phase after the injection of gadoxetic acid. one case showed a total defect, and the other showed a peripheral ring-like enhancement without a visible central...
