Hydatid disease is a parasitic infestation caused by the larval form of the cestode worms Echinococcus. In humans, the most commonly affected organs are liver and lung. Most cysts remain clinically silent and are diagnosed incidentally or when complications occur. The incidence of hydatid disease is high in the Middle East, Australia, East and South Africa and Central Europe. In Korea, hydatid disease is rare and has been reported in a few cases. We experienced a case of multiple intraperitoneal cysts from ruptured hepatic hydatid cysts in a 35-year old man. His complaint was palpable abdominal mass and discomfort. Abdominal ultrasound and CT scan revealed multiple hepatic and intraperitoneal cysts. The surgical findings showed multiple cysts and daughter cysts. The pathologic finding of resected cyst was the characteristic pattern of outer thick laminated membrane and inner thin germinal layer. Albendazole was administrated for prophylatic purpose.

In December 2011, we reported an autochthonous case of Echinococcus multilocularis infection in a 42-year-old woman in Korea. The diagnosis was based on histopathological findings of the surgically resected liver cyst. In the present study, we evaluated the serological and molecular characteristics of this Korean E. multilocularis case. The patient's serum strongly reacted with affinity-purified native Em18 and recombinant Em18 antigens (specific for E. multilocularis) but negative for recombinant antigen B8/1 (reactive for Echinococcus granulosus). In immunoaffinity chromatography, the serum also strongly reacted with E. multilocularis and only weakly positive for E. granulosus. We determined the whole nucleotide sequence of cox1 (1,608 bp) using the paraffin-embedded cystic tissue which was compared with E. multilocularis isolates from China, Japan, Kazakhstan, Austria, France, and Slovakia. The Korean case showed 99.8-99.9% similarity with isolates from Asia (the highest similarity with an isolate from Sichuan, China), whereas the similarity with European isolates ranged from 99.5 to 99.6%.
