Colangite crônica associada à infestação de trematódeo por platynosomum fastosum, concomitante à vesícula biliar dupla em um gato

This paper aims to report a case of a 5-years-old, mixed breed cat showing severe jaundice, skin petechiae and ecchymosis, high values of ALT enzyme and serum cholesterol and low plasmatic proteins. A medical treatment was instituted; however the animal died two days after clinical intervention. Anatomicopathological analisys showed a chronic cholangitis associated with liver fluke infestation caused by Platynosomum fastosum, and duplex gallbladder. We conclude that anatomical changes associated with infestation by parasites may significantly aggravate the clinical condition of chronic cholangitis and should always be considered in the diagnostic plan.
