Minimal change glomerulonephritis associated with hydatid disease

A 63-year-old man presented to our department with dyspnea and peripheral e dema. A cystic mass in the right upper abdomen, consistent with echinococca l disease was discovered. Protenuria was also present, and a nephrotic synd rome was diagnosed. The kidney biopsy revealed minimal change glomeruloneph ritis. Treatment with the anti-echinococcal drug albendazole induced comple te remission of the nephrotic syndrome, suggesting an etiopathogenic role f or a hydatid antigen in the development of an immune-mediated glomeruloneph ritis.
