Vascular pattern on Liver Biopsy

This is probably the most difficult to recognize and ranges from very subtle to the more recognizable features associated with congestive hepatopathy. It can also share some features in common with biliary processes. If fibrosis is present, it will occur in a centrizonal pattern.

Features of a Vascular Process

  • Portal venopathy: atrophic and branching portal vasculature.

  • Sinusoidal changes- fibrosis or central vein occlusion (Think sinusoidal obstructive syndrome) , dilatation and/or sinusoidal congestion
