Isolated Hydatid Cyst of the Kidney

Abstract

Echinococcal cyst commonly involves the liver and the lungs. Renal hydatid cyst is unusual and tends to occur in association with other organ involvement. Isolated hydatid cyst is extremely rare and can mimic renal tumors. Hence, this diagnosis should be entertained in patients from endemic areas with solitary renal lesions. Although eosinophilia is a suggestive criterion, its absence should not dissuade from pursuing this diagnosis. We here describe a patient with prolonged history of lumbar pain resulting from a large hydatid cyst treated by nephrectomy with a pre- and postoperative course of albendazole and praziquantel.
