Alveolar hydatid disease causing total occlusion of the inferior vena cava.

Alveolar hydatid disease is a malignancy-like parasitic disease. It is invasive, metastatic, and almost always lethal if left untreated. A case of alveolar hyatid disease presenting with total of the inferior vena cava is reported. This 28-year-old man was referred for elevation of obstructive jaundice. He was a lama and had recently arrived in Taiwan after touring temples in Nepal, India, and Singapore. Computed tomography showed calcified mass which occupied the right hepatic lobe with extension to the left hepatic lobe. The inferior vena cava was occluded and stricture of biliary tree and portal vein at the hilum was also noted. The patient was treated successfully with palliative resection combined with postoperative albendazole. With increasing travel and immigration, clinicians will be more likely to encounter this rare disease, and thus should be able to recognize its symptoms.
