Hydatid disease (Echinococcosis) is a zoonotic infestation and it is endemic in those countries where sheep and cattle raising industry are prevalent due to close association between man, sheep and dog. Man is the accidental intermediate host. We report an isolated hydatid cyst of spleen in a young male which is an uncommon site for hydatid disease because most cases of hydatid diseases are in liver and lung.
