Congenital hepatic fibrosis in an aborted calf

ABSTRACT

An aborted female Holstein foetus with marked generalized anasarca was referred to the Excellence Centre for Ruminant Abortion and Neonatal Mortality, Ferdowsi University of Mashhad. On postmortem examination, red-tinged ascites, pale and firm liver with extreme irregularity and numerous round to oval slightly raised foci on the capsular surface were seen. Histological examination revealed widespread fibrosis, linkage of periportal areas to the central vein region and proliferation of bile ductules forming a branching network within the fibrous tissue. The lesion was diagnosed as congenital hepatic fibrosis
