Fascioliasis: A challenging differential diagnosis for radiologists

Abstract

We report a case of a 39 year old male who presented with nausea and right upper quadrant pain. Marked eosinophilia and a hypoechoic liver lesion on ultrasound were identified. The differential diagnosis included neoplasms, infectious diseases and hepatic abscess. Indirect hemagglutination test using purified adult Fasciola hepatica f1Ag confirmed serologic diagnosis of fascioliasis. Radiologists should keep in mind the importance of correlating imaging, clinical and laboratory findings in order to reach the correct diagnosis.
