A case report of human primary renal cystic echinococcosis.

In humans, solitary renal involvement or primary renal echinococcosis is rare, accounting for about 2-4 % of cases. Usually, patients shpw no obvious symptoms, but they can manifest as renal pain, renal mass, gross hematuria, and hydatiduria in rare cases. We report a case of primary renal cystic echinococcosis, which was originally misdiagnosed as a tuberculous renal abscess.
