Abstract:
A 2-year-old boxer dog from southern Ontario was evaluated because of acute onset lethargy. Exploratory laparotomy revealed a hemorrhagic, destructive, liver mass. Histology, immunohistochemistry, and polymerase chain reaction confirmed Echinococcus multilocularis as the cause of the hepatic mass. This constitutes the first description of endemic E. multilocularis in Ontario.
