Abstract
An immunocompetent child in Canada received a diagnosis of disseminated alveolar Echinococcus multilocularis infection. The case lacked typical features of liver involvement and was possibly related to a rare congenital portosystemic shunt. We summarize the rapidly evolving epidemiology of E. multilocularis parasites in Canada.

The epidemiology of E. multilocularis parasites in Canada has been rapidly evolving over the past decade
E. multilocularis parasites were detected in 23 of 91 canid carcasses collected within the Calgary and Edmonton metropolitan areas during 2009–2011 [10]
Summary
An immunocompetent child in Canada received a diagnosis of disseminated alveolar Echinococcus multilocularis infection. In Canada, the incidence of human cases of E. multilocularis is low [3]. We describe a case of disseminated AE without hepatic involvement in a child from Manitoba with a congenital portosystemic shunt, in the context of emerging epidemiology of AE in Canada. An ultrasound showed a large irregular echogenic lesion within the left kidney measuring ≈10 cm.
