Biliary parasitic diseases including clonorchiasis,opisthorchiasis and fascioliasis

Parasitic infection of the biliary tree is caused by liver flukes, namely Clonorchis sinensis and Opisthorchis viverrini. These flukes reside in the peripheral small bile ducts of the liver and produce chronic inflammation of the bile duct, bile duct dilatation, mechanical obstruction, and bile duct wall thickening. On imaging, peripheral small intrahepatic bile ducts are dilated, but the large bile ducts and extrahepatic bile ducts are not dilated or slightly dilated. There is no visible caused of obstruction. Sometimes, in heavy infection, adult flukes are demonstrated on sonography, CT or MR cholangiography as small intraluminal lesions. The flukes in the gallbladder may appear as floating, small objects on sonography. Chronic infection may result in cholangiocarcinoma of the liver parenchyma or along the bile ducts. Human infection of Fasciola hepatica, a cattle flukes, may occur inadvertently, and the flukes migrate in the liver (hepatic phase) and reside the bile ducts (biliary phase). Image findings in the hepatic phase present with multiple, small, clustered, necrotic cavities or abscesses in the peripheral parts of the liver, showing “tunnels and caves” sign, reflecting parasite migration in the liver parenchyma. In the biliary phase, the flukes are demonstrated in the intra- and extrahepatic bile ducts and the gallbladder as small intraluminal flat objects, sometimes moving spontaneously. Bile ducts are dilated.     

Three-dimensional ultrasonography using the minimum transparent mode in obstructive biliary diseases: early experience.

OBJECTIVE: To assess the feasibility of three-dimensional ultrasonography using the minimum transparent mode in patients with obstructive biliary disease. METHODS: Fourteen patients with obstructive jaundice underwent three-dimensional ultrasonography after conventional two-dimensional ultrasonography before interventional procedures. Three-dimensional images reconstructed by the minimum transparent mode were evaluated and compared with direct cholangiography. The minimum transparent mode images were compared with the two-dimensional ultrasonographic images to determine whether additional information was obtained. RESULTS: The level of obstruction was correctly depicted in all patients, and a dilated common bile duct, common hepatic duct, gallbladder, and main intrahepatic ducts were well visualized on minimum transparent mode images. The findings on minimum transparent mode images were well correlated with those on cholangiography; however, the perspective of the whole biliary tree on minimum transparent mode images was inferior to that on cholangiography in all cases. The overall image quality of minimum transparent mode images was poor in 6 patients, fair in 3, good in 4, and excellent in 1. The biliary anatomy was more objectively visualized on the minimum transparent mode images than conventional two-dimensional ultrasonographic images. CONCLUSIONS: Three-dimensional ultrasonography using the minimum transparent mode appears to be clinically feasible. The biliary anatomy was more objectively visualized on the minimum transparent mode images than conventional two-dimensional ultrasonographic images. Further technical development is needed to improve imaging resolution.

Intrabiliary rupture of hepatic hydatid cyst: multidetector-row CT demonstration

Rupture of a hydatid cyst into the biliary tract, also known as cystobiliary communication, is the most common complication of hepatic hydatid cyst. This may lead to obstructive jaundice, pancreatitis, cholangitis, and sepsis with high mortality. Imaging plays an important role in the preoperative diagnosis of this condition which facilitates its management. We studied six patients with rupture of hepatic hydatid cyst into a large bile duct in whom multidetector-row CT (MDCT) suggested the diagnosis. The imaging findings included a single hepatic cyst less than 10 cm in diameter in all the cases; interruption of the cyst wall adjacent to a bile duct signifying cyst-bile duct communication was seen in five patients. The common bile duct was dilated in all the patients, with linear membranes in four and diffuse irregular high dense intrabiliary material observed within the common bile duct in two of them. Intrahepatic ducts were dilated in all the six cases and two patients showed linear dense contents within distended gallbladder. Subcapsular and intrathoracic rupture was associated in one patient each. MDCT demonstration of hydatid cyst in the liver together with a dilated common bile duct and distended gallbladder containing high density hydatid material suggest rupture of the cyst into biliary tree. MDCT enhances demonstration of the dilated common bile duct with hydatid material inside. The diagnosis is reinforced by the demonstration of the cystobiliary communication itself.
