Abstract: Renal pelvis leiomyomas are very rare benign neoplasms that derive from smooth muscle cells. These tumors occur in vessels and in the urothelial mucosa of urinary tract. This report describes a 50-year-old woman with a contrast enhanced lesion in the right renal pelvis, measuring 20 × 23 × 25 mm, which was found incidentally during an abdominal-pelvic CT scan. Histopathologic analysis of a cold biopsy revealed a chronic inflammatory process without dysplasia. The mass was resected percutaneously; it was diagnosed as a leiomyoma. Only 13 cases of ureteral leiomyoma have been reported to date; to our knowledge, this is the first such tumor resected using a percutaneous approach.
