Fig. 2.

A 21-year-old man presented to the emergency department with a 1-week history of upper abdominal pain, pruritus, and jaundice. Laboratory tests revealed increased levels of serum amylase, lipase, and acute phase reactants. Serological tests for E. granulosus were positive. a, b Axial gray-scale US images demonstrate the imaging findings of intrabiliary rupture of a hydatid cyst (asterisk). The right main bile duct and choledochal duct are dilated due to cyst contents (arrows, a, and b). ce Axial contrast-enhanced CT images reveal hydatid cyst (asterisk) and associated wall irregularity (arrowheads) due to intrabiliary rupture. Note biliary dilatation (short arrows, c and d) and also increased attenuation levels of the right main bile duct due to cyst contents (long arrow). CT image at the level of pancreas demonstrates peripancreatic fat tissue stranding (arrows, e) compatible with acute pancreatitis
