Cholangitis describes an inflammation of the biliary tract. Cholangiohepatitis describes the inflammation of the biliary tract and the surrounding hepatic parenchyma. It is typically categorised into [[Cholangitis, Neutrophilic|Neutrophilic Cholangitis]] and [[Cholangitis, Lymphocytic|Lymphocytic Cholangitis]].
==Signalment==
Cholangitis is common in cats, where a periportal hepatocellular necrosis is seen together with
the presence of neutrophils in the portal area. Cats can be acutely or chronicaly affected, and
male, pure bred cats are most overly prepresented.
The condition is also seen in calves as a secondary condition to bacterial infection, such as Salmonella.
