Renal Hydatidosis

Renal hydatidosis is a rare manifestation of echinococcal disease, accounting for only 2-3% of all hydatid infections. We present the case of a 21-year-old female with no typical risk factors who presented with a large renal hydatid cyst. The patient reported a four-month history of progressive abdominal distension in the right hypochondrium extending to the right flank, accompanied by oppressive pain, nausea, vomiting, fatigue, anorexia, and weight loss. Imaging studies confirmed a large renal hydatid cyst in the upper pole of the right kidney. The patient underwent preoperative treatment with albendazole followed by successful surgical management with partial nephrectomy and cyst enucleation. This case highlights the importance of considering hydatid disease in the differential diagnosis of cystic renal masses, even in patients without typical epidemiological risk factors, and demonstrates the efficacy of a combined medical and surgical approach.
