Hydatid cystic disease at unusual sites

Hydatid disease is a zoonotic infection caused by Echinococcus granulosus, which belongs to phylum Platyhelminthes. It is endemic in many parts of the world including India. Though Hydatid disease commonly occurs in liver and lung no organ or tissue is immune in the body. When it presents in unusual sites Hydatid disease often poses a diagnostic challenge. A high index of suspicion, comprehensive radio imaging investigations are often required to evaluate these cases. In the study we have conducted for 4 years, we reported a total no of 7 Hydatid cases that presented at unusual sites. Most common rare presentation in our study was renal hydatid disease, 3 cases; and one each in pancreas, Spleen, peritoneum and pelvis.
