Invasiveness of hepatocellular carcinoma and cholangiocellular carcinoma with their radiographic appreciation as hepatomegaly has been reported [ 7 ], whereas inflammatory diseases or neoplasia, hepatic venous congestion, fat infiltration, cholestasis, cirrhosis, infiltrative diseases amyloidosis or lipidosisand storage diseases have been described as the potential causes of diffuse hepatomegaly [ 11 ].
Diagnostic Tests and Imaging Techniques for the Hepatobiliary Affections By using a combination of history, physical examination findings, results of screening, and hepatobiliary-specific laboratory tests, ascigis clinician usually becomes apt to describe the disorder as active or quiescent.
Open in a separate window. The liver biopsy findings and histopathological examination may range from unremarkable to minimal inflammatory changes in disorders of non-cirrhotic portal hypertension [ 9 ].
The primary indication so obtained may suggest evidence of hepatobiliary disease that can be confirmed by other, more specific tests including advanced diagnostic imaging procedures. Sagittal sonogram 2D of liver in a ten-year-old intact Labrador retriever dog affected by a perianal tumour showing hyperechoic hepatic mass with central lytic changes.
Hepatic inflammation, regeneration and caninx result in the development of portal hypertension and the establishment of multiple extrahepatic portosystemic shunts which in turn promote the development of ascites [ 18 ], whereas perihepatic changes such as ascites, portal and splenic vein asciris and splenomegaly might occur with cirrhosis because of portal hypertension [ 10 ].

Despite availability of ascjtis range ascltis diagnostic tests of both hepatic damage and dysfunction, there is rarely a single test that adequately identifies hepatic disease or its underlying cause.

Sonography of the liver, gallbladder, and spleen. Histopathological Features The liver biopsy findings and histopathological examination may range from unremarkable to minimal inflammatory changes in disorders of non-cirrhotic portal hypertension [ 9 ].

Effective Management Practices to Reduce Urinalysis findings reveal bilirubinuria and absence of asfitis.
Stieger SM, Url A. Besides the presence of multiple portosystemic collateral vessels, ascites, splenomegaly, and an abnormal liver echogenicity, enlarged main portal and extrahepatic portal veins are the associated features canima portal hypertension [ 20 ].
