Figure 1 Magnetic resonance imaging showing a typical large focal nodular hyperplasia in 2005 (A-C) with complete spontaneous regression after 7 years of follow-up (D-F). Gd-BOPTA-enhanced magnetic resonance imaging showed a large hypervascular lesion on arterial phase imaging (A), with iso to hypoenhancement on the delayed venous phase (B), and uptake of Gd-BOPTA on the 2 h delayed hepatobiliary phase (C). Note the central scar inside the lesion (white arrow). In 2012, MRI with the same contrastographic sequences demonstrated complete resolution (D-F), with residual subcentimeter scarring (red arrow).
