Platinosomiasis is a parasitic infection caused by the trematode Platynosomum spp., found in the liver of domestic felines. The feline is the definitive host of Platynosomum, and the severity of the disease depends on the amount of parasites, time of parasitism and host response. The aim of this work was to report a case of post-hepatic jaundice resulting from feline platinosomiasis. A male, young, mixed breed feline was presented with a history of severe jaundice, progressive weight loss and sudden death. A sample of the bile content was collected and analyzed by sedimentation through centrifugation to search for helminth eggs, resulting in the observation of innumerous dark brown, oval, monoperculated and embryonated eggs, morphologically compatible with eggs of Platynosomum. The stereoscopy of fresh liver samples and histopathology confirmed the parasitism through the identification of adult specimens, whose morphological features were compatible with Platynosomum illiciens. The post-hepatic jaundice was related to bile stasis resulting from the accumulation of intraductal mucus and parasites. In this particular case, the pathological findings associated with the identification of adults recovered from the biliary content were essential for the definitive diagnosis of the disease.
