A case of benign renal hemorrhagic cyst in a 73-year-old man is reported. Ultrasonography, computed tomography and magnetic resonance imaging revealed a solid mass in the left renal cyst. Percutaneous puncture of left renal cyst was carried out followed by endoscopic biopsy of the intracystic masses. Specimens showed no malignancy. As we could not rule out malignancy, left partial nephrectomy was performed. The surgical specimen was free from malignancy by pathological examination. Thus endoscopic biopsy of intracystic tumor indicated the correct diagnosis.
报告了一例73岁男性的良性肾出血性囊肿病例。超声检查、计算机断层扫描和磁共振成像显示左肾囊肿内有一个实性肿块。对左肾囊肿进行了经皮穿刺，随后对囊内肿块进行了内镜活检。标本显示无恶性病变。由于我们不能排除恶性肿瘤的可能性，因此进行了左肾部分切除术。病理检查显示手术标本无恶性肿瘤。因此，对囊内肿瘤进行内镜活检可得出正确诊断。
