[A patient with alveolar echinococcosis (Echinococcus multilocularis infection]

In a 45-year-old Swiss male, who had been living in the Netherlands for 20 years, alveolar echinococcosis was diagnosed. He had probably been infected during his youth in Switzerland. His illness became symptomatic more than 20 years later. The diagnosis was reached by microscopic examination of material obtained from a necrotic mass in the liver. Imaging revealed that the disease had spread diffusely throughout the liver, spleen and abdomen. Curative resection was impossible. Percutaneous drainage of the hepatic necrotic mass was complicated by a bacterial infection for which he was treated with antibiotics. Treatment with high doses of albendazole resulted in considerable improvement. The patient represents the first case of Echinococcus multilocularis infection diagnosed in the Netherlands.
