Ultrasonography is an excellent noninvasive way to evaluate liver parenchyma. Villiers E, Blackwood L, editors. The most common types of primary hepatic cancer reported in male dogs are hepatocellular carcinoma and intrahepatic cholangiocellular bile duct carcinoma in female dogs.

Dogs affected by this condition are mostly young or middle aged adults of either sex with signs of hepatitis of varying severity. A small-sized liver is a frequent radiographic appreciation with any type of vascular anomaly [ 8 ].

Veterinaria Machado ; 24 Oct 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.

Markedly increased and abnormally variable portal blood flow velocity with attenuated intrahepatic portal vessels and localized dilatation of the intrahepatic portal vein PV at the site of communication with the caudal vena cava CVC may be detected in congenital intrahepatic portosystemic shunts.

Diagnostic Imaging of Canine Hepatobiliary Affections: A Review

Ascifis tests can be very useful in diagnosing hepatic affections, with the exception of those patients, who are icteric. Diseases of the liver and biliary tract. Large liver lobes in hepatomegaly in acute hepatic insults often have rounded margins, whereas the normal liver lobes have sharp edges [ 26 ].

Laparoscopic-guided percutaneous Tru-Cut needle biopsy of hepatic mass in 8-year-old intact male Labrador Retriever dog. Sonographic Features Portal hypertension is difficult to diagnose with standard ultrasound imaging. Vomiting is a consistent sign with acute toxic hepatopathy. With idiopathic chronic hepatitis, the inflammation extends into the hepatic lobule, causing piecemeal necrosis of hepatocytes [ 9 ].

Microhepatica may be appreciated radiographically with chronic biliary obstruction in dog leads to biliary cirrhosis [ 89 ]. Radiographic Features A small-sized liver is a frequent radiographic appreciation with any type of vascular anomaly [ 8 ]. The hepatic parenchymal echogenicity in canines with acute hepatic failure may range from normal to diffusely mottled to decreased echogenicity [ 23 ].

So, the faecal specimen analysis must be conducted although it rarely provides useful information in the evaluation of the dog with suspected ascitks affection. 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 ]. 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 Biliary Tract Disorders Disorders of biliary tract comprise of the diseases of the biliary tract itself e.

Two-dimensional ultrasonographic appearance of liver in sagittal scan depicting hyperechoic parenchyma with rounding of liver lobe surrounded with textured fluid ascitix a 6-year-old male Labrador Retriever affected with infectious peritonitis.

Hepatomegaly is reliable radiographic sign cannina liver disease which may be diffuse, with uniform enlargement of all lobes or focal, with enlargement of only a single lobe [ 11 ] Figure Etiology In idiopathic chronic hepatitis, it is probable that after an initial inciting hepatocyte injury, immune mechanisms are involved in perpetuating the inflammation [ 8 ].

Sonograph 2D in transverse scan showing hyperechoic liver lobe and cholecystitis with inspissated bile in gall bladder GB in a 7-year-old intact Pomeranian male dog. Cirrhosis can be visualized sonographically as increased hepatic echogenicity accompanied with less distinct appearance of the echogenic portal vein margins and decreased distal visualization.

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 ].

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. Right lateral radiograph of a nine-year-old spayed female, German shepherd dog revealing hepatic nodular masses on the caudal visceral margins of right liver lobes irregular. Cholangiohepatitis and cholecystitis is most commonly associated with ascending infection [ 1 ].

DIROFILARIA CANINA by juan david rojas muñoz on Prezi

In idiopathic chronic hepatitis, it is probable that after an initial inciting hepatocyte injury, immune mechanisms are involved in perpetuating the inflammation [ 8 ]. Double rim effect of gall bladder wall in cholecystitis has also been reported [ 26 ].

Liver involvement is also common in canines with lymphoma. Disorders of biliary tract comprise of the diseases of the biliary tract itself e.

This type of ascites is typically a manifestation of advanced cancers of the organs in the abdominal cavity, such as, colon cancerpancreatic cancerstomach cancerascitus cancer… Compendio de enfermedades de los caninos y felinos Ultrasonic imaging in liver disease: Scintigraphy nuclear imagingmagnetic resonance imaging MRIand computed tomography have recently been used in the diagnosis of hepatobiliary affections, but the need for radioisotopes and expensive equipment has restricted their use to the teaching institutions of developed nations.

Great thanks in advance! Prevalence of gall bladder sludge in dogs as assessed by ultrasonography.

Diagnostic Imaging of Canine Hepatobiliary Affections: A Review

It offers tremendous advantage of direct visceral visual inspection of liver and allows its descriptive acsitis photographic documentation. The clinical signs and clinicopathologic features of acute toxic hepatopathy are not distinct from other hepatopathies except in onset and perhaps in severity. Whereas, in congenital extrahepatic portozygos shunt, the shunting vessel runs roughly ascjtis to and on the left of the abdominal caudal vena cava and could be followed to the diaphragm without communicating with the caudal vena cava [ 21 ].
