A 32-year-old female patient presents to the sonography

a. Choledocholithiasis
b. Cholangitis
c. Mirizzi syndrome

b. Choledocholithiasis
c. Caroli syndrome

b. Mirizzi syndrome
c. Choledochal cyst
d. Biliary atresia

All of the following are clinical findings consistent with
cholangiocarcinoma except:
