Abstract

Supernumerary kidneys are rare congenital anomalies arising from abnormal renal development, with fewer than 100 cases documented in the literature. A 55-year-old male presented with chronic nonbloody diarrhea and was diagnosed with a locally advanced rectal tumor. A staging CT scan incidentally revealed a right-sided supernumerary kidney measuring 4.5 cm, alongside a larger right kidney (7.3 cm) and a normal left kidney (10.2 cm), with independent arterial supply and normal excretory function. While this finding did not impact the patient's oncological treatment plan, awareness of such anomalies is essential for surgical planning to avoid complications. This case underscores the importance of recognizing supernumerary kidneys to guide clinical decision-making in oncological and urological interventions.

在分期 CT 扫描中意外发现的多肾：罕见病例报告

超常肾是肾脏发育异常引起的罕见先天性畸形，文献记载的病例不到 100 例。一名 55 岁的男性出现慢性非血性腹泻，被诊断为局部晚期直肠肿瘤。分期 CT 扫描偶然发现了一个 4.5 厘米长的右侧多余肾脏，旁边还有一个更大的右肾（7.3 厘米）和一个正常的左肾（10.2 厘米），肾脏有独立的动脉供应，排泄功能正常。虽然这一发现并没有影响患者的肿瘤治疗计划，但了解此类异常情况对于手术规划以避免并发症至关重要。本病例强调了识别超常肾脏对指导肿瘤和泌尿科干预临床决策的重要性。
