Hydatid disease is a parasitic infection caused by cystode, EG which is a tape worm causing endemic disease in many parts of world mainly in India3,4. The disease in man is caused by infection of larvae of the tape worm which reside in digestive system of dog (definitive host) after reaching the duodenum of man (intermediate host), the chitinous layer of the larvae is digested and released oncospheres pass through portal circulation, spreads to the liver, lungs and other organs and form cystic lesions3,4,5,6. The life cycle of the parasite is completed when intermediate host dies and body is consumed by definitive host.
