Despite of being a relatively rare disease in horses, cholelithiasis is the most common cause of biliary obstructionin this species. Simultaneous intrahepatic and extrahepatic gallstones are the most frequent presentation. Usually, there areno clinical signs associated with this condition, although biliary obstruction could occur as a consequence. Two cases ofcholelithiasis in horses, including gross and histopathological findings are described. In one of the cholelithiasis cases therewas no association with clinical signs or cause of death, but in the other one, chronic loss of weight may have been causedby cholelithiasis.(AU)
