Introduction: Hydatid disease is endemic in many parts of the world. Urinary tract involvement develops in only 24% of all cases, and isolated renal cysts are extremely rare. Renal hydatidosis in children is rare. There are no specific signs or symptoms that will reliably confirm the diagnosis of renal echinococcosis. A serological markers are not sensitive for the diagnosis of a hydatic cyst, it may be confused with a cyst in the organ involved. We wanted to emphasize the importance of keeping in mind the possibility of hydatid disease in cystic renal lesions, particularly in endemic regions.
Case report: A 13-year-old female was admitted to our clinic with a 3-month history of moderate preumblical pain. During the last 20 days, these symptoms had worsened. There was no history of recurrent urinary tract infection, calculi, or lower urinary tract symptoms. On physical examination, we found abdominal tenderness, and systemic examination was unremarkable. Urinalysis and results of laboratory studies were within normal range. A detailed history was obtained from the patient. She had been living in Zahedan city, and her family raised livestock. She had a history of contact with sheep and cattle. Ultrasound revealed a cortical cystic mass 9×8cm in size at the left kidney, but do not including multiple small cysts with internal echo. Computed tomography confirmed this lesion. It showed a unilocular cystic lesion without internal septa which originated from the left kidney and bulged superiorly to the kidney. Liver and other abdominal structures were all normal. Chest films were also normal.
The patient underwent surgical exploration of the left kidney with flank incision. After ruling out malignancy and the diagnosis of a renal hydatid cyst, the whole cyst layers were removed. During the postoperative period, albendazole treatment was started. Pathological examination confirmed the diagnosis of a renal hydatid cyst.
Conclusions: To conclude, this case emphasizes that hydatidosis should be considered in the differential diagnosis of any cystic lesion, especially in regions where it is endemic.
To avoid misdiagnosis, a careful examination of cystic lesions in kidneys should be carried out in endemic areas for the detection of hydatid cysts.
