Answer

In patients with chronic HCV infection, inflammatory cells accumulate in the portal tracts. They may also have foci of inflammation accompanied by necrosis in the parenchyma. Subsequently, the margins of the parenchyma and liver tracts become inflamed, and liver cell necrosis results.

Ultimately, if the infection progresses, inflammation and necrosis may lead to fibrosis. Mild fibrosis is confined to the portal tracts and adjacent parenchyma, whereas severe fibrosis is associated with bridging between the portal tracts and hepatic veins.

Eventually, fibrosis can progress to cirrhosis, when the fibrous septa separate the liver into nodules.
