MRI images. Focal oval lesion straddling segments III and IVb showing sharp contours, heterogeneously high signal in T2 (A) and in diffusion-weighted imaging (B) corresponding to heterogeneous hypersignal on ADC map (C). Irregular and globally hypoenhancing behavior on T1 portal venous phase (D). (E) The lesion was located inferiorly to segmental left portal bifurcation, displaying a contact with the segmental branch for segment III without any major distortion or infiltration.

During resection, the tumor was found to be in contact with the left hepatic duct, which was confirmed by a perioperative cholangiography and a left hepatectomy was performed (Figure 2).
Sclerosed hemangioma, histological appearances. A rich paucicellular fibrous (F) stroma is distinguished from the Normal liver (L) tissue. Irregular vascular channels (VC) are separated by endothelial cells with thin fibrous septa (S). (A) Histology. Hematoxylin-eosin, magnification x40. (B) Histology, Hematoxylin-eosin, magnification x100.
