The possible causes of focal hepatic enlargement include cysts, granulomas, abscesses, neoplasia, regenerative nodules, haematomas, and rarely liver lobe torsion [ 7 ].

Etiology Causes of acute hepatic failure in canines include hepatotoxins, infectious and parasitic agents, and miscellaneous disorders [ 8 ]. Normal-appearing hepatic angiogram, demonstrating jejunal mesenteric vein normally draining into the portal vein and the extensive portal vein branches in1-year-old male mixed-breed dog. Ultrasonography of abdominal cavitary parenchymal lesions.

Symmetrical changes in hepatic volume in hepatomegaly can be estimated by measuring the maximal distance from the caudal tip of the liver on the ventral midline till the diaphragm. Besides, ultrasound-guided percutaneous hepatic biopsy allows precise direction of the biopsy needle to the area of abdominal tissue while avoiding large vessels, the gall bladder, and the gastrointestinal tract [ 5 ].

Primary hepatic neoplasia has a variable sonographic appearance ranging from a very large, moderately circumscribed, infiltrating mass bulging beyond ascifis normal liver margins with an canona slightly more mixed than normal liver [ 43 ]. Latent hepatic viral infection with canine adenovirus type I, which is responsible for infectious canine hepatitis ICHis also suspected to cause persistent inflammation and thus chronic hepatitis [ 9 ].

Dorsal sonogram 2D of liver depicting hypoechoic parenchyma with portal vessel dilatation in one-year-old mixed-breed asciti. Three unusual diseases of primarily young dogs, that is, hepatoportal fibrosis, idiopathic hepatic fibrosis, and caninaa hypoplasia of portal vein might be grouped under this title. Hepatomegaly is reliable radiographic sign of liver disease which may be diffuse, with uniform enlargement of all lobes or focal, with enlargement of only a single lobe [ 11 ] Figure Laboratory Evaluation Microcytosis is a common feature vanina this disorder.

A small-sized liver is a frequent radiographic appreciation with any type of vascular anomaly [ 8 ]. Other potential findings include hyperbilirubinemia, increased SBA concentration, hypoglycaemia, hyperammonemia, and coagulopathy. Manual of Clinical Onco- logy. Causes of acute hepatic failure in canines include hepatotoxins, infectious and parasitic agents, and miscellaneous disorders [ 8 ].

In familial chronic hepatitis, H and E-stained ccanina tissue reveals dark granules in hepatocyte cytoplasm in centrilobular hepatocytes in the early stages and generalized in later stages [ 9 ].

Liver Biopsy and Histopathological Examination Liver biopsy is often required to definitely characterize the nature and severity of the hepatic disease.

Disorders of biliary tract comprise of the diseases of the biliary tract itself e. Clinical Manifestations In cholecystitis, the clinical signs include asctiis, lethargy, fever, canima pain, vomiting, diarrhoea, and septic shock due to septic bile peritonitis following acute rupture of gall bladder.

Dogs with cholelithiasis are often asymptomatic and clinical signs jaundice, anorexia, weight loss, vomiting, and dehydration are most likely when cholelithiasis is complicated by bacterial infection, EBDO, perforation of the gall bladder or bile ducts [ 8 ]. The most common types of primary hepatic cancer reported in male dogs are hepatocellular carcinoma and intrahepatic cholangiocellular bile duct carcinoma in female dogs.

Ultrasonographic features of canine hepatic nodular hyperplasia. The desirable virtues of less time consumption and noninvasive assessment of the detailed internal architecture of the liver and the adjacent structures, including the portal vein, established ultrasonography as the choicest technology, for identifying the various forms of hepatic disease in canines [ 2 ].

Who could help me? Hepatic lymphoma has been sonographically characterized by decreased hepatic echogenicity in canines [ 22 ], whereas a solitary hyperechoic mass has been described as the most common appearance of canine hepatocellular carcinoma [ 42 ].

However, mild cholangitis and cholecystitis are common [ 8 ].

The gall bladder wall, owing to cholecystitis gives thickened appearance due to visualization of both the inner and outer walls and is perceived as double rim effect [ 30 ]. Etiology The most common patterns of portovascular anomaly are single-extrahepatic communications between the portal vein or one of the mesenteric veins and the caudal vena cava or asvitis vein in small-breed dogs and patent ductus venosus in large-breed dogs [ 9 ].

Radiographic Features The irregular hepatic silhouette has been documented as a radiographic feature of nodular hyperplasia [ 7 ], whereas focal hepatic enlargement can be detected by bulge ascitls alteration in the hepatic margin or the localized displacement of the fundus, cania body, pylorus, right kidney, cranial duodenal flexure, transverse colon, and head of the spleen or diaphragm [ 16 ].

La ascitis en asciits – Causas y tratamiento – ExpertoAnimal ; 14 Jul Familial chronic hepatitis in Bedlington terriers, Dobermann pinschers, West Highland White Terriers and Skye Terriers have a hereditary autosomal recessive inability to excrete copper in the bile that is associated with progressive hepatic copper accumulation and chronic liver disease [ 9 ].

Focal nodular hyperplasia lesions have been documented as well defined solid masses having a variable, often greater echogenicity than the normal liver parenchyma, and a central highly echogenic area. Histopathological Features Diffuse hepatic necrosis is the primary histologic lesion most consistently associated with acute hepatic failure [ 8 ].
