A case of large renal hydatid cyst.

Isolated renal echinococcosis is a rare acquired disease of the kidney, caused by the parasite Echinococcus. The kidneys are involved in less than 2 % of all human hydatidosis; isolated renal involvement is even rarer. Based on the clinical and radiological findings, diagnosis of a rare case of isolated renal echinococcosis was made. The diagnosis was confirmed by laparoscopic surgery and histopathology.
