Abstract:
Fever of unknown origin (FUO) is recognized as fever with uncertain diagnosis despite three days of hospital admission or three or more outpatient visits.[1] Acute liver fluke infection is characterized by fever, right upper quadrant pain, hepatomegaly, jaundice, and peripheral blood eosinophilia. By contrast, chronic liver fluke infection is asymptomatic in its early stage, but can easily progress to cirrhosis, cancer, or bile duct cancer in its later stages. The diagnosis of clonorchiasis is particularly challenging in non-endemic areas. We herein report an unusual case of liver fluke infection in a patient who presented with FUO and eosinophilia.
