Renal Hydatid: Rare Site of Rare Disease

Echinococcosis is a parasitic infection caused by the larval stage of a cestode Echinococcus granulosus. It manifests as hydatid cyst.

Infection is transferred through the oral-fecal pathway by eggs of the parasite. Hydatid cyst can be made in liver, lung and rarely in heart, breast, thyroid, soft tissue of neck and kidney.

Herein, we present a case of hydatid cyst of kidney, a rare organ to get infected by Echinococcus granulosus. Our patient, presented with dull vague pain & heaviness in left flank, got diagnosed with hydatid cyst of left kidney on radiology. Nephrectomy was performed, in view of non- functional nature of kidney.
