PURPOSE: We present a rare case of perirenal hemangioma that was detected incidentally. METHODS/ RESULTS: Radiographic examinations revealed a 3.5 cm mass at the left renal hilum adjacent to the left renal parenchyma, which was difficult to differentially diagnose from renal cell carcinoma. Tumor resection was performed successfully. CONCLUSIONS: There was no recurrence observed 14 months after surgery.
