UNCOMMON LOCATIONS OF HYDATID-DISEASE - CT APPEARANCES

Hydatid disease (HT), already known by Hippocrates, is prevalent and w idespread in most sheep-raising countries in Asia, Australia, South Am erica, Near East, and southern Europe. The disease is most commonly du e to Echinococcus granulosus and may occur in any organ or tissue. The location is mostly hepatic (75 %) and pulmonary (15 %), and only 10% occur in the rest of the body [1]. Imaging modalities such as US, CT, and MR imaging are helpful in diagnosing the disease. The reliability of each method depends on the cyst's location in the body [2-5]. The p urpose of this essay is to illustrate the use of CT in depicting some unusual locations of HD besides the liver and lung.
