XXXX 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 @entity1087 , @entity788 , @entity255 , and @entity295 with high mortality. Imaging plays an important role in the preoperative diagnosis of this condition which facilitates its management. We studied six @entity1 with @entity397 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 @entity1 . The common bile duct was dilated in all the @entity1 , 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 @entity1 showed linear dense contents within distended gallbladder. Subcapsular and intrathoracic @entity397 was associated in one @entity1 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 @entity397 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.
