"The lung is the second most common site of involvement with Echinococcus granulosus in adults (~16%) after the liver (~65%), but may be the most common site in children 1. The coexistence of liver and lung disease is unusual, < 6% of patients 2."

"Cysts are protected and fed through compressed host tissue which forms a fibroinflammatory pericyst, and they may grow, up to 1 or 2 cms annually. Early cysts contain mobile protoscolices, hooklets and calcareous corpuscles (hydatid sand); E. granulosus forms endogenous brood capsules (daughter cysts), which subsequently degenerate, with detachment of the germinal and laminar layers of the endocyst which may float in the fluid (water lily sign). The cysts may leak or rupture causing secondary pleural or pericardial hydatidosis via scolex dissemination and implantation, and may also cause anaphylaxis. The mother cyst may eventually dry out and calcify 11."
"Although Echinococcus granulosus presents commonly with unilocular cysts, Echinococcus multilocularis and Echinococcus vogeli may cause alveolar and polycystic echinococcosis. Exogenous daughter cysts are more typical of E. multilocularis."
