Hydatid disease remains endemic in various parts of the world due to the close association that exists between sheep, dogs and humans. Humans are the accidental intermediary hosts in the biologic cycle of the Echinococcus granulosus, which is the most frequent hydatidosis in the environment. USG and CT are both excellent imaging modalities for the detection of hydatid cysts. CT provides 3-D view and delineates the cyst, which is useful when diagnosis is uncertain, or when rupture or infection has occurred.
