Abstract
Background: Multicystic nephroma is a rare entity of cystic renal tumor, it is a benign non-hereditary pathology with an excellent prognosis, whose preoperative diagnosis is often difficult. Only the anatomopathological study can confirm this. Case Presentation: 54-year-old patient, having consulted for right low back pain evolving for 6 months without any other associated sign. The clinical examination objectified a slight tenderness of the right lumbar fossa. Abdominal ultrasound revealed a 6 cm multi-partitioned cystic renal mass. The uroscanner identified a right mid-renal cystic mass with multilocules containing fine and regular partitions, with exo-renal development measuring 66*74 mm classified Bosniak IIF. A resection of the entire cyst by lombotomy was performed, the histological examination of which came back in favor of a multicystic nephroma. Conclusion: The discovery of a cystic renal tumor often represents a source of uncertainty as to its potential for malignancy. The definitive diagnosis can only be made after surgical management with histological study.
