Abstract
BACKGROUND
Coexisting gallbladder stones, common bile duct stones andClonorchis sinensis infection is rare. Most radiologists
and surgeons have low awareness and diagnostic suspicion of C.
sinensis infection before opting for surgery.
CASE SUMMARY
A 39-year-old man was admitted to our department with complaint of right
upper quadrant abdominal pain of 5 h duration. Physical examination
revealed tenderness in the upper right abdomen and a positive Murphy
sign. Increasing transaminase and bilirubin levels were the major
laboratory findings. Preoperative imaging showed gallbladder stones, a
common bile duct stone with slight dilatation of the intrahepatic bile
ducts, and a blurred lower common bile duct. During surgery, an active
parasite was found in the common bile duct. The final diagnosis was
cholelithiasis with comorbid C. sinensis infection.
CONCLUSION
Preoperative imaging that reveals nonspecific changes associated with
choledocholithiasis should increase suspicion of biliary parasite
infection.
