Doshi and K.M. Mehta Institute of Kidney Diseases and Research Centre (IKDRC), Ahmedabad, Gujarat, IndiaAbstract: Renal involvement, which can rarely occur in echinococcosis, more commonly manifests as hydatid cyst of the kidney. Scattered case reports of nephrotic syndrome secondary to hydatid cyst in the liver or lung have been reported for over two decades. The glomerular picture varied from minimal change lesion to mesangiocapillary glomerulonephritis. We report a case of predominantly tubulointerstitial nephritis with mesangioproliferative glomerulonephritis in a patient with hepatic hydatid cyst which responded to cyst resection alone.
