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.
