Isolated renal hydatid cyst presenting as haematuria in a 35-year-old Female: A Case Report

Hydatid disease, caused by Echinococcus granulosus, is a parasitic infection that primarily affects the liver and lungs, with renal involvement being rare. This case report describes a 35-year-old female who presented with right flank pain and occasional hematuria. The patient had a history of close contact with a pet dog. Imaging studies, including ultrasound and computed tomography (CT), revealed an 8 cm hydatid cyst in the right kidney. Serological testing confirmed the diagnosis of renal hydatid disease. The patient underwent preoperative albendazole therapy followed by partial nephrectomy. The postoperative course was uneventful, and the patient showed no recurrence at three months follow-up. Renal hydatid disease, although uncommon, should be considered in patients from endemic areas or with relevant risk factors. Early diagnosis through imaging and serological tests, followed by a combination of medical and surgical management, can lead to successful outcomes. This case highlights the importance of considering hydatid disease in the differential diagnosis of renal cystic masses in appropriate clinical settings.
