Peliosis hepatis is an uncommon disease characterised by irregular blo
od-filled cystic spaces in the hepatic parenchyma; it is often accompa
nied by telangiectasis (dilatation of the sinusoids) although this may
also occur separately. The cause is unknown but the condition occurs
in a range of species including man, cattle and dogs and a single case
has been reported previously in a cat. In this report of 18 cases in
cats, there had been intra-abdominal haemorrhage in 11 of them.
