An unusual case of biliary obstruction caused by Dicrocoelium dentriticum.

Dicrocoelium dentriticum (D. dentriticum) is a liver fluke induced biliary obstruction. Infection usually occurs in herbivores such as sheep, goats and deer; human infection is very rarely encountered in clinical practice. We report on a 65-y-old female presenting with biliary obstruction caused by D. dentriticum. Following treatment with triclobendazole, her symptoms disappeared, and laboratory values returned to normal range within 6 months. Parasitosis is an important cause of biliary obstruction. We suggest that for patients presenting with biliary obstruction, D. dentriticum should be included in the differential diagnosis.
