Figure 1

Preoperative image findings (case 1). (A) Computed tomography without contrast enhancement. A cystic lesion, 15 cm in diameter, is seen in the medial segment and right lobe. The lesion is multilocular, consisting of several separated lesions. The tumor is adjacent to the right side of the umbilical portion of the portal vein (umbilical portion is indicated by arrow heads). (B) T2-weighted, (C) contrast-enhanced, and (D) diffusion-weighted magnetic resonance imaging. T2-weighted image showed the cystic lesion in the medial segment and right lobe. On the section presented here, three separated lesions are seen (indicated by a, b, and c). Contrast enhancement showed that each separated lesion contained multiple papillary nodular components with enhancement. Cystic lesion (a) contains a tiny nodule inside (indicated by an arrowhead), cystic lesion (b) has a papillary nodular component in its posterior side (indicated by arrowheads), and lesion (c) was filled with papillary nodular components. A diffusion-weighted image showed diffusion restriction in the nodular components in the lesion of (b) and (c) (indicated by arrows).
