AA positive serological testBCommunication of the cyst with the biliary treeCA single cyst in the right lobeDA cyst with a visible, well-defined wall

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Communication of the cyst with the biliary tree

PAIR with a scolicidal agent is contraindicated if the cyst communicates with the bile ducts, because the agent can enter the biliary system and cause sclerosing cholangitis. Perioperative albendazole is given to reduce the risk of spillage and recurrence.

Option by option

A. A positive serological test
Serology only supports the diagnosis.
B. Communication of the cyst with the biliary tree (correct)
Correct. Biliary communication makes injection of a scolicide dangerous.
C. A single cyst in the right lobe
A solitary accessible cyst is a suitable target.
D. A cyst with a visible, well-defined wall
A well-defined wall is the usual appearance of a suitable cyst.
