Isolated renal hydatid cyst in a diabetic postmenopausal female.

Isolated renal hydatid disease is very uncommon and is usually an unexpected disclosure during radiological imaging. Since it affects the kidney, renal mass, or colic, hematuria, pyuria, and dysuria are the predominant symptoms. We present a case of a 48-year-old diabetic postmenopausal female incidentally diagnosed with an isolated giant renal hydatid cyst while evaluating the cause of recurrent flank pain.
