Magnetic resonance imaging (MRI) findings. a T2-weighted image with fat saturation showing a heterogeneous hyperintense mass in segment 2 of the right hepatic lobe. b T1-weighted image showing the lesion with a homogeneous low signal intensity. c–f Gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging findings. c Marked heterogeneous high signal intensity in the arterial phase of the dynamic gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging scan. d The signal intensity is relatively reduced in the portal venous phase, but slightly higher than in the surrounding liver parenchyma, with an enhanced vascular signal visible in the lesion. e The signal intensity of the tumor is lower at the parenchymal phase than in the surrounding liver parenchyma. f A lack of gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging uptake is noted in the hepatobiliary phase at 40 minutes postinjection. Arrowheads denote tumor lesion in segment 2 of liver
