Radiographic features
The radiological features of intrabiliary rupture of a hepatic hydatid cyst can be classified into direct and indirect signs which can be seen on CT, ultrasound, and MRI. However, studies have shown increased value of MRCP in diagnosis.
Direct signs
direct visualization of cystobiliary communication
Indirect signs
break in cyst wall adjacent to a bile duct
cystic material within the biliary tree or gallbladder
distorted shape of cyst representing reduced intracystic pressure secondary to rupture
presence of gas-fluid or fat-fluid level within the cyst
displacement of bile ducts due to extrinsic pressure
beak-like projection of cyst wall
