Gallbladder mucocele causing biliary obstruction in two dogs: ultrasonographic, scintigraphic, and pathological findings.
Two dogs were found to have intraluminal gallbladder masses which caused partial or complete extrahepatic biliary obstruction. On histological examination, the gallbladder masses were confirmed to be mucoceles. Gallbladder mucoceles are rare in humans and previously have been described only after gallbladder rupture in two dogs. In the dogs of this report, the biliary obstruction was relieved by cholecystectomy. Each dog also had histological evidence of chronic liver disease with intrahepatic cholestasis. The clinical diagnosis of biliary obstruction was based on scintigraphic and sonographic findings which will be discussed and compared with other hepatobiliary diseases.
