Hydatid disease invading the inferior vena cava: Successful combined medical and surgical treatment

Echinococcus granulosus disseminates to sites other than the liver in up to 10% of patients with hydatid disease.1 This occurs usually when a primary hydatid cyst ruptures, releasing daughter cysts into the microcirculation. The resulting metastatic disease is often inoperable and incurable. We describe a case in which direct invasion of the inferior vena cava (IVC) by a hepatic hydatid cyst led to multiple pulmonary lesions. The management of this case illustrates combined medical and surgical treatment, including a novel surgical approach, with remission of extensive disease.
