Ultrasonographic Features Acute hepatic failure may be characterized by hepatomegaly with normal, increased or decreased parenchymal echogenicity along with diffuse parenchymal abnormalities wherein the discrete hepatic borders are not visualized [ 22 ].

There may be complete loss of abdominal detail with septic bile peritonitis [ 9 ]. Abstract Hepatic disease is often treatable and has a predictable prognosis when a definitive diagnosis is made. In idiopathic chronic hepatitis, it is probable that after an initial inciting hepatocyte injury, immune mechanisms are involved in perpetuating the inflammation [ 8 ]. Besides, other systemic conditions like immune-mediated haemolytic anaemia, surgical hypotension, hypoxia, shock, acute pancreatitis, and extrahepatic bacterial infections pneumonia, pyometra, peritonitis, and abscesses can also cause severe hepatic injury [ 8 ].

Transverse sonogram 2D of right medial liver lobe of two and half-year-old intact female Pointer dog depicting generalized hyperechoic parenchyma with biliary sludge in gall bladder. Hepatodynia is a feature with any cause of acute hepatic injury, whereas fever and acute abdominal pain are presenting signs of acute pancreatitis, cholangiohepatitis, and hepatic abscess [ 89 ].

Cholangiohepatitis and cholecystitis is most commonly associated with ascending infection [ 1 ]. In addition to this, many biochemical tests are not specific indicators of liver disease, but do offer a crude assessment of liver status, or aid recognition of diseases that either mimic the clinical signs of liver disease or actually cause secondary liver disease. The diffuse hypoechoic hepatic parenchyma and rounded liver margins with hepatomegaly have been documented in acute hepatic failure as varied sonographic findings ranging from normal to diffusely mottled or decreased echogenicity [ 2326 ] Figure However, mild cholangitis and cholecystitis are common [ 8 ].

Portal hypertension may be secondary manifestation of right-sided congestive ascitia failure, caudal vena cava obstruction, and intrahepatic obstruction [ 19 ].

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 ]. Stieger SM, Url A. Abdominal ultrasonography in small animals: The abdominal effusion so obtained is analysed by subjecting it to gross examination, cytological examination, and microbiological examination.


This paper describes the different diagnostic methods and imaging techniques employed in diagnosis asvitis hepatobiliary affections in dogs.

It can be further used to differentiate acute from chronic adcitis, to stage neoplastic disease and to assess response to therapy. Two-dimensional ultrasonographic sagittal scan of right liver lobe in seven-year-old mixed-breed intact male dog showing noncystic cavitary lesions with generalized increase in parenchymal echogenicity.

Sagittal sonograph 2D of liver with extensive noncystic cavitary lesions in hepatic parenchyma canija a nine-year-old intact male Boxer dog. The complete blood count CBC is an integral part of the diagnostic investigation of any systemic disease process or for that matter of hepatic affections. Ascites, defined as the presence of fluid in the perito The selection of the biopsy method also depends on likelihood of surgical resection of a mass, tolerance of general anaesthesia, available equipment and expertise of the clinician [ 2 ].

Disorders asciti biliary tract comprise of the diseases of the biliary tract itself e. 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.

In suspected cases of hepatic neoplasia, thoracic films to evaluate the pulmonary metastasis are also desired. Ascotis ascitis en perros – Causas y tratamiento – ExpertoAnimal ; La ascitis en perros – Causas y tratamiento. Portal hypertension is difficult to diagnose with ascigis ultrasound imaging. It is important to interpret all results in light of the other aspects of the diagnostic investigation, in particular the history and physical examination.

Noncystic cavitary lesions have been described as mixed areas of anechoic, hypoechoic and hyperechoic patterns resulting from neoplasia [ 35 ]. The liver plays a central role in the coagulation and fibrinolytic systems, and subtle abnormalities may be detected by assay of individual factor activities.

Laparoscopic-guided percutaneous Tru-Cut needle biopsy of hepatic mass in 8-year-old intact male Labrador Retriever dog. Hepatic ultrasonography in the dog. Histopathologic Features The most common types of primary hepatic cancer reported in male dogs are hepatocellular carcinoma and intrahepatic cholangiocellular bile duct carcinoma in female dogs.


It is seen that laparoscopy provides better liver biopsy tissues than any other traditional percutaneous methods especially when the liver is small [ 1 ]. Monnet E, Twedt DC. However, radiographic appreciation of reduced liver size microhepatica is more difficult than hepatomegaly [ 11 ] Figure 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 ].

Furthermore, systemic diseases and various drugs can cause qscitis increases in serum activities secondary or reactive hepatopathiesand it can be a clinical dilemma to decide whether liver enzyme elevations are significant, and whether they represent primary or secondary liver disease [ 2 ].

Two-dimensional, gray-scale ultrasonography for assessment of hepatic caninz splenic neoplasia in the dog and cat. Abdominocentesis Analysis of abdominal ascitus is an important component of diagnosis. 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.

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.

National Center for Biotechnology InformationU. The stomach is distended with gas, which provides contrast with the liver shadow.

Journal of Small Animal Practice. Noncystic cavitary lesions e. Hepatobiliary diseases in the cat; pp. Who is online Users browsing this forum: 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 azygos vein in small-breed dogs and patent ductus venosus in large-breed dogs [ 9 ].

Author information Article notes Copyright and License information Disclaimer. Lateral abdominal radiograph of an 8-year-old intact male, mixed-breed dog with cutaneous tumour and pulmonary metastasis demonstrating generalized hepatomegaly.

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.
