Evaluation of Ultrasonography as a Diagnostic Tool for Hepatic Cystic Echinococcosis in Sheep
This study aimed to gain information about ultrasonographic findings in sheep with hepatic cystic echinococcosis as well as to evaluate the use of ultrasonography for diagnosis of such infection.furthermore.clinical,hematological and biochemical variations were also investigated.This study was conducted on 22 sheep of both sexes.which classified into two groups according to their liver health group (healthy liver = 13 and cystic liver = 9).Ten sheep were slaughtered and a comparison between ultrasound and post-mortem results was done.Biochemically,serum concentrations of 7-glutamyl transferase,aspartate aminotransferase,total bilirubin,and globulins were significantly increased (P<0.01),while alhumin was lowered (P<0.01)in sheep with cystic liver.Ultrasonographic findings of diseased sheep livers revealed presence of rounded.anechoic and unilocular hydatid cysts with ellipse circumference ranged from 6 to 10 cm.The borders of cysts were mostly well defined.The interior of cysts contained echogenic particulate materials,septations,or fine echoes.At the lOth intercostal space,all of ventral margin,size,thickness,and angle of livers were higher in sheep with hepatic cysts than healthy ones (P<0.01 ),while the diameter of portal vein was lesser in sheep with liver cysts than control ones (P<0.01 ).Furthermore in comparison with healthy liver group,at 9th intercostal space,the circumference of gall bladder was lowered in sheep with hepatic cysts (P<0.01).The sensitivity,specificity,positive and negative predictive values of ultrasonography for diagnosis of hepatic hydatid cysts were 80% and 100%,100%,and 83%,respectively.In conclusion,as an objective non-invasive practical tool,ultrasonography alone or in combination of some biochemical parameters reflecting liver function could be helpful for diagnosis of hepatic hydatid cysts in sheep.
