Liver transplantation in management of alveolar echinococcosis: two case reports

Hepatic alveolar echinococcosis is an infectious disease caused by the larval stage of Echinococcus multilocularis, which grows primarily in the liver of an infected person and develops as a tumorlike lesion. In advanced cases, the organisms infiltrate every organ neighboring the liver and spread hematogenously to distant organs such as lungs and brain. Surgical resection and liver transplantation are accepted treatment options for early and advanced disease, respectively. Herein, we present case reports of 2 patients with advanced alveolar echinococcal disease that invaded both lobes of the liver and neighboring vital structures including the inferior vena cava. Despite the technical difficulty of the surgery, both patients were successfully treated with living donor liver transplantation. Liver transplantation should be accepted as a life-saving treatment of choice in patients with alveolar echinococcosis for whom there is no other medical or surgical treatment options.
