Canadian-acquired hydatid disease: A case report.

Echinococcal cysts are unusual in Canada, and most cases seen are in immigrants. In northern Canadian communities, Echinococcus granulosis infection occasionally is acquired from dogs that feed on the entrails of caribou or moose. Seventeen patients with Canadian-acquired hydatid cysts were seen over an 11-year period. One challenging case is described in detail. An 18-year-old aboriginal woman presented with jaundice, pain, lower extremity edema and coagulopathy from a 26 cm echinococcal hepatic cyst. She was successfully treated with a combination of oral albendazole, percutaneous drainage and surgery. One-year follow-up showed no recurrence of disease. The management options for echinococcal cysts are extensively reviewed.
