Polycystic liver disease in golden hamsters.
Seven cases of multiple hepatic cysts of varying sizes and shapes were recorded in a closed colony of golden hamsters. Ante-mortem examination failed to show any clinical signs except for abdominal enlargement in one hamster. Multiple, thin-walled cysts of varying sizes (0.25 to 3.0 cm) and shape were observed in the liver. The larger cysts protruded from the liver surfaces and contained a colourless, clear, serous fluid and caused pathological change in 5-60 per cent of the hepatic parenchyma. Microscopically, the cysts were uni- or multilocular and lined by low cuboidal or flattened epithelial cells. The hepatic parenchyma around cysts showed pressure atrophy, necrosis, engorged sinusoids or other blood vessels or even haemorrhages, mild to extensive fatty or vacuolar degenerative changes and occasionally proliferation of biliary ducts.
