An 80-year-old man was accidentally diagnosed with a left renal pelvic tumor by computed tomography (CT), and visited our hospital. A tumorous lesion with an inhomogeneous contrast effect occupying the left renal pelvis was confirmed by the contrast-enhanced CT scan, and enlargement of multiple lymph nodes around the aorta and inferior vena cava was recognized. Urine cytology of the left renal pelvis was pseudo-positive. In the preoperative diagnosis of left renal pelvic carcinoma cT3N2M0, left nephroureterectomy and lymph node dissection were performed. Pathological findings revealed an amyloid tumor confined to the renal sinus and diagnosed as localized amyloidosis.
一名80岁男性因计算机断层扫描（CT）意外诊断出左肾盂肿瘤，遂来我院就诊。增强CT扫描证实左肾盂有一个具有不均匀强化效应的肿瘤性病变，同时发现腹主动脉和下腔静脉周围多个淋巴结肿大。左肾盂尿液细胞学检查呈假阳性。术前诊断为左肾盂癌cT3N2M0，遂行左肾输尿管切除术及淋巴结清扫术。病理结果显示为局限于肾窦的淀粉样瘤，诊断为局限性淀粉样变性。
