Pathologic findings of the explanted liver. The right lobe appears to be rather small compared with the left lobe (a). On the cut surface, vague nodularity is discernible on the right side (b), whereas nodularity is obscure on the left side (c). The right portal vein (RPV) became narrowed. Metallic probe indicates a narrowing site (d). A low-power view (×1.25 objective) showing nodules surrounded by a fibrous septum in the right lobe (e Masson’s trichrome stain), and a poorly demarcated and rather pale area of nodularity resulting from hyperplastic changes in hepatocytes with sinusoidal dilation, surrounded by incomplete fibrous bridging and atrophic areas of the hepatic parenchyma in the left lobe (f Masson’s trichrome stain). A dilated small-sized peripheral portal vein, protruding into the hepatic parenchyma (g Masson’s trichrome stain) and sinusoidal dilatation (h H&E stain), consistent with portal hypertension, is observed. Interlobular portal veins showing luminal narrowing and occasional dilatation, with intimal thickening (black arrow) (i, j Masson’s trichrome stain)
