Isolated Unilocular Renal Hydatid Cyst

Abstract

Hydatid disease is endemic in many parts of the world. The location of the cyst is mostly hepatic (75 %)and pulmonary (15 %), and only 10 % of the cysts occur in the rest of the body. Although hydatidosis canbe present in all parts of the body, urinary tract involvement develops in only 2-4 % of all cases, andisolated renal cysts are extremely rare. There are no specific clinical symptoms or signs that will reliablyconfirm the diagnosis of renal echinococcosis. In addition, there is no laboratory finding that ispathognomonic for hydatid disease except for hydatiduria. Routine blood tests are generally normal exceptfor eosinophilia which is found in only 50 % of the cases. Radiological studies have a more importantplace in the preoperative diagnosis of renal hydatid disease. We present herein a patient with isolated renalhydatid disease presented as left upper quadrant mass treated successfully with complete excision of thecyst and preservation of the kidney.
