Human hepatic capillariasis is a rare disease, which predominantly affects children aged 1 to 4 years and has a poor prognosis in extensive infections. This is the first case observed in Germany. The main symptoms are those of severe parasitosis: persistent high fever, hepatomegaly, and excessive hypereosinophilia. Diagnosis is confirmed by the finding of intracellular typical eggs in liver biopsy. There is a lack of established therapy; our 18 months old girl developed liver fibrosis. She survived under a prolonged treatment with high doses of Thiabendazole and two single doses of Ivermectine. Decortin was given to inhibit further granulomatous processes in the liver.
