Renal hydatid cyst mimicked cystic renal cell carcinoma: A case report

Hydatid cyst (HC) is a zoonotic parasitic disease in agricultural and pastoral areas while renal involvement without liver and lung hydatid is both less common in clinical practice and rarely described in literature. We present a case of a 40‐year‐old male from Xinjiang who complained of flank pain in the right with oliguria. Robot‐assisted laparoscopic exploration, conversion to open laparotomy and excision of internal capsule in right kidney were performed. Finally, a typical renal HC was diagnosed after complementary examinations. Isolated renal HC is very rare and can be misinterpreted as a cystic renal cell carcinoma pre‐operatively.
