Cystic echinococcosis of the liver associated with repeated international travels to endemic areas.

Cystic echinococcosis (CE) is increasingly seen in immigrants from endemic areas to Western countries; however, it is rarely reported in short-term travels to endemic areas. This is partly because the echinococcal cyst typically grows slowly and may long remain clinically silent. We describe a case of cystic echinococcosis in a man born and living in a nonendemic urban area in North Italy that was acquired during a period of frequent travels in highly endemic countries.
