Changes

A coarse or nodular texture to the liver on ultrasonography.  However, most have variable or no detectable changes in echogenicity of the liver parenchyma.  More chronic cases may have dilation of the biliary tract.

===Cytology and Histopathology===

===Histopathology===

Liver cytology or tissue biopsy is required to differentiate inflammatory liver disease from hepatic lipidosis and neoplasia.  Bile samples for cytology is needed for a definitive diagnosis.  It is not adequate to perform liver biopsy alone as the disease tend to be confined to the biliary tract and pathology of the liver can be non specific and  mild.  Cytologically, neutrophilic cholangitis usually shows bacteria and neutrophils.  Culture and sensitivity should be performed for appropriate choice of antibiotics.
