A 59-year-old
woman presented with
abdominal pain. Abdominal computerized
tomography was suggestive of biliary stones. During
endoscopic retrograde cholangiopancreatography,
adult worms resembling
Clonorchis sinensis (C. sinensis) were drained.
Eggs were detected in stool using the
formalin-
ether concentration
method and C. sinensis-specific antibody was detected in the
serum. A
diagnosis of C. sinensis
infection was made. The symptoms of the
patient gradually resolved
after treatment with anti-
parasite medication. The
patient lived in a non-endemic region for C. sinensis
infection and had no
history of intake of raw or undercooked
freshwater fishes.
South Korea is one of the endemic countries for C. sinensis
infection and people can be infected via indirect routes of
transmission such as
cooking utensils. Therefore, the possibility of C. sinensis
infection should be considered in
patients presenting with biliary
diseases in
South Korea. We describe the clinical findings of this case with a
review of
literature.
