Fasciola hepatica in the Differential Diagnosis of a Patient with Obstructive Jaundice and Eosinophilia.

Fasciola hepatica is a trematode that is visible to the naked eye. The diagnosis can be made by serology or by clinical improvement and decrease of eosinophilia after triclabendazole treatment or by finding parasite eggs in the stool. Sometimes the diagnosis is possible during unnecessary surgery, laparoscopic cholecystectomy, and endoscopic retrograde cholangiopancreatography (ERCP). F. hepatica infection should be considered in patients with typical clinical findings; the elevation of liver enzymes indicating cholestasis, eosinophilia, and characteristic computed tomography (CT) or ultrasonography (USG) findings. Here, we presented a case with the preliminary diagnosis of choledocholithiasis and diagnosed with F. hepatica infection by ERCP procedure.
