Multiple Leberherde und Eosinophilie – ein Fallbericht einer Fasciola hepatica-Infektion

Abstract

Fascioliosis is a zoonotic disease caused by Fasciola hepatica (common liver fluke). Initial clinical symptoms are frequently non-specific. Even after the development of liver tumors, a range of different underlying disorders will have to be considered. The rare cause of a parasitosis is not always included in the differential diagnostic work up. We report on a 41-year-old truck driver from Middle East who was admitted at our hospital due to ongoing upper abdominal pain, fatigue, night sweat and nausea lasting for weeks. Diagnostic investigation showed leucocytosis, high erythrocyte sedimentation rate, elevated liver values and IgE as well as blood eosinophilia. Radiological findings of the computed tomography were bilateral pulmonary lesions 3 mm in size and multiple hepatic lesions up to 4.5 cm in diameter. Due to the suspicion of a malignant disease, a liver biopsy was planned but cancelled after parasitological serology (Western blot and ELISA) revealed IgG-antibodies against F. hepatica. Detailed history gave evidence of a recent parasitological infection during a stay in Turkey with consumption of vegetable which were grown and washed with water from the local river. Eggs of the parasite could neither be found in analysis of duodenal secretion nor in examination of fecal culture. However, confirmation for the infection with F. hepatica was proved with another positive serology. The treatment with Triclabendazole (Egaten(®)) for two days with a total dosage of 2000 mg was followed by a remarkable recovery of the patient's symptoms and decrease of eosinophilia in the blood count just one month after treatment and normalization after four months.
