On reaching the duodenum of the intermediate host (man, sheep, cattle and camel), the shell of the egg is digested liberating onchospheres which penetrate the intestinal wall and reach the blood circulation. The onchospheres are then carried to different parts of the body and get encysted. The liver is the most favoured site where the majority of the cysts settle down. However, other parts of the body such as lungs, spleen, brain, heart, kidneys, bones, abdominal cavity and musculature may also contain the hydatid cysts.
