Primary hydatid cyst looked like renal cell carcinoma: case report

Irzi Mohamed et al. J Surg Case Rep. .

Abstract

Renal hydatid cyst is a rare disease comprising of about 2-3% of all locations. We present a case of renal hydatid disease in a 48-year-old female patient who presented with a history of left flank pain without fever or hematuria. Ultrasonography and computed tomography showed a 3-cm cystic lesion Bosniak IV occupying the mid-zone of the left kidney diagnosed as renal malignancy. Laparoscopic partial nephrectomy was performed, but the histopathological examination of the lesion revealed hydatid cysts. Isolated renal hydatid cyst is very rare, especially in developed countries and can be misdiagnosed as a renal cell carcinoma pre-operatively.

Keywords: differential diagnosis; renal cell carcinoma; renal hydatid cyst.
