RESUMEN
Hydatid cyst is a parasitic disease caused by the tapeworm Echinococcus granulosus. Hydatid cyst disease mostly involves the liver and the lung, while renal involvement is rare. Hydatid disease may present in unusual ways and lead to diagnostic diffi culty and management problems. A high index of suspicion for hydatid disease should be maintained while evaluating complex cystic renal masses. Herein we present an interesting case who was diagnosed to have a simple renal cyst on contrast-enhanced computed tomogram, which turned out to be a renal hydatid cyst. Despite modern imaging methods, isolated renal hydatid disease might still cause diagnostic dilemma and hydatid cysts can be found in unusual localization. Th is case was managed laparoscopically.
