Ruptured hydatid cyst: An unusual cause of pneumobilia

Abstract

Echinococcosis or hydatid disease caused by the larval stage of cestodes of the genus Echinococcus granulosus, produces cystic lesions in various organs, the liver being the most common site. Symptoms are produced by mass effect, biliary obstruction, or secondary infection in most instances. Cystic rupture is an uncommon cause of symptoms. We report the uncommon occurrence of pneumobilia in the setting of hydatid cyst rupture with secondary infection by gas producing organisms.
