[Echinococcus multilocularis infection - six cases during two years in Sweden]

Abstract

Alveolar echinococcosis (AE) caused by the fox tapeworm Echinococcus multilocularis is a zoonosis presenting with focal liver lesions and has a poor prognosis without treatment. The disease is common in Central and Eastern Europe but has been highly unusual in Sweden. A suspicion of AE usually arises through radiology and the diagnosis may be confirmed by histology and/or serological antibody detection. AE is treated with radical surgery in combination with anti-helminthic drug therapy. During the last two years six cases of AE have been diagnosed in Sweden. In no case was AE suspected clinically before biopsy. A heightened awareness of AE is needed among Swedish physicians, including radiologists, surgeons and pathologists.
