Upper digestive stenosis due to a hydatid cyst of the liver.

Unlabelled: The complications of the hydatid cyst of the liver are dominated by infection and rupture. The compression of adjacent organs (mainly the inferior vena cava, the portal vein and the bile ducts) can be seen, when the cyst is located in the dome, in the hilum or within the hepatic parenchyma. Upper digestive stenosis by compression of the duodenum by the hydatid cyst is an exceptional complication.
