Dynamic magnetic resonance imaging (MRI) of the liver (A-C, 3D T1-weighted gradient echo image) and histology of surgical specimens (D, E). A 6.4 cm-sized main mass (arrow) showed heterogeneous rim-enhancement throughout arterial (A), portal (B), and delayed phase (C), and small nodule (arrowhead) in the right lobe also showed rim enhancement. D: A moderately differentiated cholangiocarcinoma (immunohistochemical staining of Filamin-A). E: An Edmondson-Steiner grade I, trabecular type hepatocellular carcinoma. (H&E, D: ×200, E: ×100).
