The larval form of Echinococcus granulosus (tapeworm), which causes hydatid cysts, penetrates the intestinal mucosa and settles in tissues and is contracted through animal contact or other ways. The most common location is liver, and renal involvement is very rare. It is usually diagnosed with nonspecific symptoms or incidentally. A kidney lesion was incidentally detected in a 55-year-old female patient who was suffering from chronic diseases and underwent partially nephrectomy. We aim to present this case in which renal hydatid cyst was diagnosed with the help of literature because of its rarity.
