A 10-year-old cat was admitted to the Jardim da Saúde Veterinary Center with a history of anorexia, prostration and jaundice. On physical examination, it was observed an abdominal enlargement. The ultrasound revealed polycystic liver disease and biliary duct obstruction. During cholecistoduodenostomy, several cystic structures were observed within the liver. Bile cytology was performed revealing the presence of Platynosomum fastosum eggs. Findings were consistent with Platynosomum fastosum infection associated with polycystic liver disease. Although uncommonly mentioned, infection by Platynosomum fastosum should be placed as a differential diagnosis in polycystic liver disease in cats, always taking into account the geographic location and the hunting habits of the cat.
