Renal hydatid cyst presenting as an intrarenal-pelvic mass

Abstract

Intra-renal-pelvic hydatid cyst is a rare manifestation of renal hydatid disease, as most of the renal hydatid cysts are based in the renal cortex. We present and discuss the clinical and radiological findings of a 55-year-old woman who presented with left flank pain, frequency, dysuria, and hydatiduria. She was thoroughly investigated radiologically, and the diagnosis of intra-renal-pelvic hydatid cyst was confirmed surgically.
