Intravenous pyelography revealed presence of a space-occupying lesion in the lower pole of right kidney with curvilinear calcifications. Ultrasound, computed tomography and MRI were suggestive of hydatid cyst in the right kidney. Patient underwent right-sided nephrectomy. Passage of hydatid cysts in urine is an exceedingly rare occurrence. Urinary tract involvement develops in 2-4% of all cases of hydatid cyst. Hydatiduria is an extremely rare manifestation of renal hydatid cyst. We report such a case with emphasis on IVU, sonographic, CT and MRI findings. %K hydatid cyst %K hydatiduria %K hydronephrosis %K multiloculated %U http://www.radiologycases.com/index.php/radiologycases/article/view/128
