Fig. 4From: Living donor liver transplantation for idiopathic portal hypertension with extrahepatic portal vein stenosis and splenic artery aneurysms: a case report and review of the literatureHistologic feature of the explanted liver. a Nodular regenerative hyperplasia (NRH) was noted in the liver explants. Parenchymal nodularity created by areas of hypertrophic hepatocytes in periportal areas alternating with areas of cord atrophy without fibrosis (H&E stain). b Same field of view as A by Masson trichrome stain. c Obliterative portal venopathy was seen in this portal tract, in which there is a diminished-caliber and almost sclerotic portal vein (H&E stain). d Incomplete septal cirrhosis was observed in this slide. Here, fibrous bands (arrows) extend from the portal tract and end blindly in the liver parenchyma (Masson trichrome stain)Back to article page
