UNUSUAL LOCATIONS OF HYDATID CYST

The most common sites of hydatid disease (HD) are represented by the l iver and the lungs. in 10% of cases, HD arises in unusual viscera : ma inly spleen (0.9 to 8%) and also kidney, bones, heart, brain, peritone um (0.5 to 5%). Other exceptionnal location was described in less than 1% of ail cases of hydatid cysts. Ultrasonography and CTscan are high ly suggestive of HD, while serologic tests are variable. The cysto-per icystectomy is the gold standard procedure but sometimes unsuitable fo r particular sites. In that cases a conservative approach (partial per icystectomy) is mandatory to preserve the organ function. The place of adjuvant medical treatment remains questionable.
