Diagnostic Imaging of Canine Hepatobiliary Affections: A Review

Clinical Manifestations Age range of affected dogs of either sex is 2 months to 8 years; most are presented when less than 1 year old. Presently, laparoscopy is also emerging as a fruitful imaging modality. Diagnostic tests for the hepatobiliary system; pp. Biochemical findings often prove to be the most useful aid in the diagnosis of hepatobiliary affections. European Association for the Study of the 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 ].

Liver Biopsy and Histopathological Examination Liver biopsy is often required to definitely characterize the nature and severity of the hepatic disease. It is particularly useful in differentiating focal from diffuse disease, cystic from solid masses and obstructive from nonobstructive icterus [ 5 ].

Severe diffuse hepatomegaly can be easily demonstrated on lateral radiographic projections as substantial portion of the caudal liver margin projecting beyond the costal arch along with rounding of the caudal liver edges.

Age range of affected dogs of either sex is 2 months to 8 years; most are presented when less than 1 year old. The ascitiz of survey radiography in detecting the alteration in liver size has been widely emphasized. Noncystic cavitary lesions have been described as mixed areas of anechoic, hypoechoic and hyperechoic patterns resulting from neoplasia [ 35 ]. Biliary Tract Disorders Disorders of biliary tract comprise of the diseases of the biliary tract itself e. This paper describes the different diagnostic methods and imaging techniques employed in diagnosis of hepatobiliary affections in dogs.

There may be complete loss of abdominal detail with septic bile peritonitis [ 9 cainna.

Laparoscopy Laparoscopy offers tremendous advantage of direct visceral visualization three-dimensional of the liver and adjacent structures such as the pancreas and extrahepatic biliary tract.

Diseases of the spleen. Hepatomegaly can be radiographically evidenced as increased distance between the stomach and diaphragm or caudal displacement and ventral covering of ascihis right kidney by the liver [ 39 ].

Ultrasonography is an excellent noninvasive way to evaluate liver parenchyma. Abstract Hepatic disease is often treatable and has a predictable prognosis when a definitive diagnosis is made. Great thanks in advance! Two-dimensional, gray-scale ultrasonography for assessment of hepatic and splenic neoplasia in the dog and cat.

Histopathological Features Liver biopsy most consistently reveals hepatocyte atrophy with small or absent portal veins. Furthermore, systemic diseases and various drugs can cause misleading increases in serum activities secondary ascitsi reactive cxninaand it can be a clinical dilemma to decide whether liver enzyme elevations are significant, and whether they represent primary or secondary liver disease [ 2 ]. Laparoscopy may reveal very small 0. Radiographic Features Radiographic findings depend on the underlying cause of obstruction and may include cholelithiasis with radiopaque densities in the area of gall bladder or bile duct, emphysematous cholecystitis, pancreatitis, and mass lesion [ 8 ].

Hepatic disease is often treatable and has a predictable prognosis when a definitive diagnosis is made. Selection of the best procedure for obtaining a liver biopsy depends on numerous factors including liver size, presence of coagulopathy, any focal or diffuse lesion, presence of biliary tract obstruction, or any other intra-abdominal abnormalities.

Ultrasonography of the liver. It is preferred to percutaneous techniques when excess bleeding is expected and to laparotomy when delayed wound healing hypoalbuminaemia is anticipated. Vomiting is a consistent sign with acute toxic hepatopathy.

Diagnostic Imaging of Canine Hepatobiliary Affections: A Review

Two-dimensional ultrasonographic sagittal scan of right ascitiis lobe in seven-year-old mixed-breed intact male dog showing noncystic cavitary lesions with generalized increase in parenchymal echogenicity. Visualization was enhanced by the negative contrast provided by air in gastric fundus.

Cholecystitis in a dog-ultrasonographic diagnosis. Noncirrhotic Portal Hypertension Three unusual diseases of primarily young dogs, that is, hepatoportal fibrosis, idiopathic hepatic fibrosis, and primary hypoplasia of portal vein might be grouped under this title.

A definitive diagnosis of hepatobiliary affection should be confirmed by hepatic biopsy and histopathological examination. Ultrasonographic features of canine hepatic nodular hyperplasia. The presenting complaints are polyuria and polydipsia, urate urolithiasis, and anaesthetic ascitjs sedative intolerance.
