Ultrasonographic findings in cattle and buffaloes with chronic hepatic fascioliosis

The purpose of this study was to characterize the ultrasonographic findings in cattle and buffaloes with chronic hepatic fascioliosis. To the best of the author's knowledge, this report is the first to document ultrasonographic findings in buffaloes with chronic hepatic fascioliosis. Ultrasonographic findings included distended gallbladders with either homogenous or heterogeneous contents, edema of the gallbladder walls, which ranged from mild or moderate to severe and bile duct mineralization. In 78\% of the buffaloes, there was an ultrasonographic picture of hepatic fibrosis in which heterogeneous and hyperechogenic hepatic parenchymas with multiple echogenic foci were imaged. Other ultrasonographic findings included peritoneal, pleural and pericardial effusions. Two cows and one buffalo were slaughtered and examined postmortem. Hence, it was possible to verify distended gallbladders, edema of the gallbladder wall, calcified bile ducts, cholestasis and hepatic fibrosis by using ultrasonography in the cows and buffaloes with chronic hepatic fascioliosis. The procedure offers a useful supplement to clinical, hematological and biochemical examinations on the diagnosis of this condition.
