The various infectious causes of acute hepatic failure include leptospirosis, toxoplasmosis, histoplasmosis, and infectious canine hepatitis. However, lack of abdominal contrast and insensitivity to detect subtle changes limits the precision of abdominal radiography.

Chronic pancreatitis with extra peritoneal fluid collection misleadingly Passive congestion observed in acute hepatic insult is the most common benign cause of diffuse decreased liver echogenicity which result from dilatation of hepatic sinusoids and hepatitis, owing to swelling of hepatocytes [ 24 ] Figure Diagnostic laparoscopy in dogs: The vanina test results are typical of mild, moderate, or severe hepatocellular damage, suggested by high-serum ALT activity and variable increases in ALP activity [ 8 ].
